Racer on Rails at Portland: Heat, Heart, PRO3 Lessons, and Runoffs Testing at The Dash for Kids

Portland International Raceway has a way of making club racing feel bigger than the lap chart.

Maybe it is the setting. PIR sits inside Delta Park in North Portland, tucked into one of the more unique pieces of motorsport geography in the country. Long before it became a racetrack, the land was Vanport, a wartime city built to house Kaiser shipyard workers during World War II. At its peak, Vanport was home to nearly 40,000 people and was the second-largest city in Oregon. In 1948, the city was destroyed by flooding. Years later, the remaining street grid helped form the bones of what would eventually become Portland International Raceway, with the first Rose Cup race held in 1961.

That history matters. PIR is not just another track carved into an empty field. It is a public park, a community gathering place, and one of the great regional motorsports homes in the Pacific Northwest. It is flat, fast in places, technical in others, and just awkward enough to reward drivers who can get the car rotated, settled, and back to power without wasting motion.

For this weekend, Racer on Rails returned to PIR with Cascade Sports Car Club for an ICSCC Conference race weekend, The Dash for Kids XLII.

For anyone newer to Northwest club racing, ICSCC, often simply called โ€œConference,โ€ is the International Conference of Sports Car Clubs. Founded in 1957, it is an association of independent sports car clubs across Oregon, Washington, and British Columbia, and it remains one of the core regional racing structures in the Pacific Northwest. One of the things that makes Conference special is that it is very much club-powered. Drivers are represented through their member clubs, and those clubs participate in the governance of the series. It creates a regional racing culture that feels practical, involved, and very connected to the people actually building, towing, fixing, flagging, and racing the cars.

Cascade Sports Car Club is one of those foundational clubs. Cascade began in 1953 as the 4-Cylinder Sports Car Club of Oregon, changed its name to Cascade in 1956, and has grown into a club with a year-round schedule that includes track days, driver education, road racing, rallies, and volunteer support for major events at PIR.

The Dash for Kids is one of Cascadeโ€™s signature weekends. It blends Conference championship road racing with a community charity event, including race car rides, paddock access, family activities, and fundraising for local organizations. The 2026 event marked the 42nd running of The Dash, with race car rides offered during lunch on Saturday and Sunday for donations to the charity.

That meant this weekend had two lanes of purpose for us.

One lane was competition and development.

The other was community.

And, by the end of the weekend, we got a full serving of both.

The Racer on Rails Plan

Originally, we expected to have three drivers on the weekend but one driver had to bow out last minute which left us with two primary competition programs. The silver lining was that open third slot gave us an opportunity to bring out the Racer on Rails #136 Spec E46 race car to give some lunch time charity rides! Can’t complain about that!

For Ron, the goal was not results-first. The goal was development-first.

Ronโ€™s larger arc this season has been about building the kind of adaptable driving skill that transfers across platforms. He has driven Spec E46, the Porsche Cayman GT4, Spec Racer Ford 3, and now PRO3. The long-term objective is not simply to be fast in one car. It is to become the kind of driver who could step into an endurance team environment and be trusted: aware, consistent, confident, mechanically sympathetic, and able to keep the car in a competitive window.

That is a very different target than chasing a single lap time.

PRO3 is an excellent tool for that kind of work.

The class began in the Pacific Northwest in 2002, growing out of a group of BMW E30 racers and friends connected to the Puget Sound BMW CCA scene. It has since become one of the strongest amateur racing classes in ICSCC, the PNW, West Coast and if the group raced nationally, it would be one of the largest racing classes at any weekend, with large grids and deep competition.

It also has a very specific personality. People often casually describe PRO3 as a spec class, and while the rules are restrictive, it is better understood as a tightly controlled, Improved Touring-based formula. The cars are BMW E30 325i chassis with stock M20B25 engines, controlled tires, and rules designed to keep the emphasis closer to the driver ability end of the spectrum rather than spending or exotic development.

More importantly, they are analog. No ABS. No traction control. No stability control. Many cars run without power steering. The braking window is narrow, the tires are easy to over-ask, and the car will absolutely tell on you if your inputs are sloppy. That makes PRO3 one of the best classrooms in Northwest racing.

It is also where Gama started racing, and that matters. We have seen it again and again: drivers who can run at the front in PRO3 tend to carry that skill into almost anything else they drive. It teaches commitment, car control, racecraft, mechanical sympathy, and humility. The car is not going to save you. You have to do the work.

For Gama and the 370Z, the weekend had a different purpose. This was a test event for the SCCA Runoffs at Road America later in the year. On paper, PIR and Road America do not look like twins. Road America is longer, faster, and more dramatic, with far more elevation change. But from a setup and systems-testing perspective, PIR still gives us useful information.

PIRโ€™s flatness, surface, braking zones, and mechanical-grip demands make it one of the best regional proxies available to us. It would not answer every Road America question, but it could answer some important ones: Do we have real pace? Can the car stay cool? Can we run hard in race conditions? Can we trust the package over a longer stint?

With hot weather forecast in the mid to high 90’s Fahrenheit across the weekend, those questions became even more relevant.

Friday: Promise for the Z, Trouble for the PRO3

Friday test day split into two very different stories.

For the 370Z, the car felt good right away. Track space was limited, and with traffic it was difficult to build a truly representative lap, but the underlying feeling was positive. The plan became straightforward: use Friday to get the car into its window, then put on a new sticker tire set Saturday morning and take two shots at qualifying.

The first shot would come in the morning mini-enduro qualifying session.

The second shot would come in Group 4, where Gama had also entered in ST. Group 4 had faster big-bore traffic, but fewer cars overall. That gave us a better chance of finding the clean air needed to see what the car could really do.

Ronโ€™s Friday was much less tidy.

The PRO3 car developed shifter issues, possibly tied to a deeper transmission issue (Note – We would later confirm the transmission itself was healthy; the shifter issue was the real culprit). Rather than force the car through a compromised test day and risk making things worse, the team made the right call: park it early, diagnose what we had, and prepare to get Ron back on track Saturday.

That kicked off one of those classic club-racing logistics adventures.

Mitchell drove back up to Seattle on Friday evening, grabbed the spare transmission from the shop, and headed back down early Saturday morning. By 7:00 a.m., the team was back under the lift, working to get the transmission into the car and get Ron back in the fight.

No velvet rope. No magic wand. Just people, tools, caffeine, and the quiet soundtrack of โ€œwell, this is what racing asks today.โ€

Saturday Morning: Thrash, Traffic, and One Clean Lap

The team got the PRO3 car back together Saturday morning, but the shifter assembly continued to fight back. It had come loose and was operating strangely enough that even after the transmission swap, there was still work to do.

The good news: the team got it functioning.

The bad news: Ron missed qualifying for both Saturday races.

That meant he would start from the back.

For a driver-development weekend, that is not always a bad thing. It is not convenient. It is not ideal. It definitely makes the day louder. But it gives a driver exactly the kind of work that cannot be simulated cleanly: traffic, starts, passes, imperfect rhythm, and the need to adapt to the car you have rather than the car you wish you had.

Meanwhile, Gama rolled into Saturday morning qualifying on new tires hoping to get a clean representative lap in the 370Z.

That part did not go to plan.

By the time we got to pre-grid, there were already more than 25 cars lined up. The decision was to go to the back and create space, but with 50-plus cars on track, including a large Spec Miata field, there simply was not enough clear racetrack to put the lap together. Then the session ended early due to an incident.

So we waited for Group 4.

This time, the track-space plan finally worked. Fewer cars. Faster traffic. A better rhythm. And then, finally:

1:23.592.

https://www.instagram.com/reel/DZnKfwEgRnP

That lap put Gama P9 overall in Group 4 qualifying and P1 in ST. More importantly, it gave us the first clean signal that the 370Z had real pace in the package.

Was it perfect? No.

There was still time left on the table. Based on feel, predictive timing, and the work Gama and Tyler had done around the carโ€™s potential, the estimate was that a 1:23.2 was likely available in that session. With a cleaner sticker-tire run and a true max-effort qualifying format, the team believes a 1:23.0, and possibly even a 1:22.8, was realistic, even in with temperatures already at 80F by 9am.

But for the goal of the weekend, the message was clear: the car had the nationally competitive pace we expected.

Now we needed to find out if it could survive the heat.

Ron Starts at the Back and Gets to Work

Ronโ€™s Saturday was the kind of day that can turn into a throwaway if the driver lets it.

He did not.

After missing qualifying, he started from the back in Group 2 and worked his way forward to P10 in a 22-car PRO3 field, with a best lap of 1:31.721.

Then he backed it up in Group 5, finishing P5 in CT4 with a best lap of 1:31.210.

That was a big deal.

Not because P10 or P5 are magic numbers by themselves, but because of how he got there. Ron had to adapt after a messy mechanical start to the weekend. He had to race from the back. He had to get close to other cars, work through battles, and keep the car moving forward.

This is exactly the kind of growth we wanted from PRO3.

In clean air, drivers can work on lap time. In traffic, they have to work on craft. Portland forced Ron into the craft side of the ledger, and by the end of Saturday he was not just circulating. He was racing people. He was putting the car in places that mattered. He was becoming more comfortable with the car moving around underneath him.

That is the good stuff.

Not shiny, not always obvious from the outside, but very real.

The 370Z Race: Pace Confirmed, Cooling Not Yet Solved

Saturday afternoon, the 370Z lined up for the Group 4 race.

The goal was not necessarily to chase the race result. The goal was to run the car hard in heat and see what we had from a reliability and cooling standpoint.

The afternoon temperatures were already brutal, climbing from around 90 degrees toward the mid-90s as the race went on. That was useful. We are unlikely to see those exact conditions at Road America in early October, but that was the point. If the car could stay cool at full tilt in this environment, we would have a lot more confidence heading into the Runoffs.

Unfortunately, the race showed us that there is still work to do.

Early on, the car was running normally in clean air. Then, after a full course yellow around six or seven laps in, water temperature warnings started to appear. The car was not done, but it was no longer free to race at full attack. Gama had to manage it with lift-and-coast into braking zones, short-shifting around 7,000 rpm, and rolling back into throttle more gently than normal.

That kept the car alive and allowed us to finish, winning ST with a best race lap of 1:24.826.

But the result was not the lesson.

The lesson was that if we had needed to battle hard, defend, attack, or run nose-to-tail for position, we would have been compromised. The pace is there. The car is closer. But the cooling system still needs more margin before Road America.

That was valuable information.

We had also entered the one-hour mini enduro, which would have been the closest proxy for the 45-minute Runoffs race distance. But with the car already showing heat-management limits, and with the afternoon only getting hotter, there was no reason to keep poking the dragon with a torque wrench.

We had learned what we needed to learn.

The team made the call to park the car for the rest of the weekend. The official results show the 370Z as a DNS for the mini enduro, which was exactly the right decision.

Sometimes the smartest lap is the one you do not run.

Sunday Morning: Ron Finds Another Gear

Sunday morning was Ronโ€™s chance to reset.

The car was back. The conditions were better than they would be later in the day. The goal was to make the most of the cooler track before the heat came in.

Ron got after it.

In Group 2 qualifying, he dropped into the 1:30s with a 1:30.946, good for P11 in PRO3.

Then, in Group 5 qualifying, he put together a 1:30.554 and qualified P1 in CT4.

Pole position. ๐Ÿ’ช๐Ÿพ

The first pole position of Ronโ€™s driving career. Let’s go!!!

That moment deserves to breathe a little.

Ronโ€™s weekend started with the car parked early, a transmission run to Seattle, a Saturday morning thrash, missed qualifying, and back-of-grid starts. By Sunday morning, he had settled himself, kept building, and put the car at the top of the CT4 sheet.

That is not just pace. That is resilience.

And in a PRO3-based car, it means something. These cars do not give you lap time for free. You have to ask the right questions with your hands, feet, eyes, and timing, then listen carefully when the car answers back.

Ron was getting more comfortable throwing the car around. More comfortable letting it move. More comfortable staying in the fight when the environment got messy.

That is the development arc.

Sunday Afternoon: Racing in the Skillet

By Sunday afternoon, PIR was hot.

Very hot.

Air temperatures were deep into the 90s, with track temperatures well above 130 degrees. No one was expecting record pace in those conditions. This was about execution, racecraft, and keeping the car underneath you while everyone else was dealing with the same greasy, overheated racetrack.

In the Group 2 PRO3 race, Ron had challengers all around him. That is what happens when you start to make your presence known. People race you differently. They expect you to be there. They fight harder.

Ron started in position, battled early, and kept working through the race. He got past the group he had been racing with the day before and finished P8 in PRO3, only a couple of seconds behind the next cluster of cars up the road. His best lap was a 1:31.354 in the heat.

P8 in PRO3 is nothing to sneeze at.

That mid-pack and front-mid-pack zone in PRO3 is filled with serious drivers. In a class that deep, moving from โ€œlearning the carโ€ into โ€œcompeting with the packโ€ is a meaningful step.

Then came the Group 5 CT4 race.

Starting from pole, Ron got mugged at the start and had to fight for the rest of the race with Payden Baxter and Matthew King. It turned into exactly the kind of race he needs more of: pressure, passing, defending, imperfect lines, and decisions that had to be made quickly.

He finished P3, on the podium, with a best lap of 1:31.164. That was barely off his Saturday CT4 race pace and impressively close to his cooler-session qualifying benchmark, considering the heat.

Mega.

A first pole. A podium. A P8 in PRO3. A weekend that began with mechanical drama and ended with real signs of competitive belonging.

Awesome work, Ron.

More Than Lap Time

The biggest thing from Ronโ€™s weekend is that the progress was not just numerical.

Yes, the lap times improved. Yes, the results got better. Yes, he put the car on pole in CT4 and ended the weekend with a podium.

But the more important part is that he had to keep the fundamentals alive when the racing got loud around him.

That is one of the hardest transitions for any developing driver. It is one thing to drive well in clean air when the plan is simple. It is another thing to drive well when someone gets alongside, a start gets messy, the car moves underneath you, or a pass does not happen in one corner.

Portland gave Ron a full buffet of those moments.

The next step is making that craft more deliberate and more repeatable. Not just being fast, but being able to access the driving under pressure. Not just getting close to cars, but knowing what to do with that closeness. Not just reacting to a battle, but shaping it.

That is exactly why we wanted him in PRO3.

Dash for Kids: The Other Reason We Were There

While the racing side of the weekend gave us plenty to work through, The Dash for Kids gave the weekend a bigger frame.

During lunch on Saturday and Sunday, racers and teams offered ride-alongs in race cars and exotic cars, with donations going toward the weekendโ€™s charity. Cascadeโ€™s format makes the paddock feel open and welcoming, with spectators able to see the cars, talk with drivers and crew, and get a closer look at the machinery that usually flashes by from the other side of the fence.

For Racer on Rails, that meant bringing down the Silver Bullet Spec E46, installing the extra seat, and joining the ride program.

After making the decision to park the 370Z, that actually became a perfect pivot. The competitive work was done. The car had told us what we needed to know. So instead of forcing more laps into worsening heat, we cooled down, reset, and had fun giving people rides around PIR.

That is a good race weekend.

Not because every plan worked perfectly. It did not.

Because the weekend gave us the right answers.

The 370Z showed pace, then showed us the next engineering problem. Ron got hit with mechanical adversity, then turned the weekend into one of his strongest development steps of the year. The team handled a transmission swap, shifter issues, hot conditions, traffic, race starts, and charity rides.

That is club racing in full color.

Final Takeaways

For Gama and the 370Z, Portland confirmed that the car has real speed. The 1:23.592 in Group 4 qualifying was the cleanest read of the weekend, and the team believes there is more available with a true max-effort qualifying format and cleaner track space. But the race also confirmed that cooling remains a priority before Road America. The car can run. The car has pace. Now it needs more thermal margin.

For Ron, Portland was a major step.

He missed Saturday qualifying, started from the back, raced forward, kept improving, put the car on pole for the first time in his driving career, finished P8 in a very competitive PRO3 field, and ended the weekend with a CT4 podium.

More importantly, he became a little more of the driver he is working to become.

Adaptable. Confident. Aware. Comfortable in the fight.

That is what we came for.

And with The Dash for Kids wrapping the weekend in community, ride-alongs, family energy, and a reminder that racing can be both serious and generous, Portland gave us exactly the kind of weekend that sticks around after the trailer doors close.

Goals. Smiles. Memories.

That one checks all three.

Portland Hoosier Super Tour Recap: Setup Windows, Mental Unlocks, and a T3 Weekend Sweep

The SCCA Hoosier Super Tour is one of the biggest stages in amateur road racing. It is where regional racers, national contenders, Runoffs hopefuls, longtime club racers, and professionally prepared teams all end up in the same paddock, chasing the same thing: speed that holds up when the stopwatch and the field both get serious.

For Racer on Rails, weekends like this matter because they are more than another race on the calendar. They are measuring sticks. They show where the cars are, where the drivers are, where the team is operating well, and where the next layer of performance is hiding.

This round brought us back to Portland International Raceway for the Oregon SCCA Hoosier Super Tour. PIR is a uniquely Northwest kind of racetrack. It sits inside a major city, close to the Columbia River, built on land with real history, surrounded by trees, planes, cyclists, and the strange calm of a public park that also happens to host serious race cars. It is one of those places that feels easy until you try to be fast there.

On paper, Portland looks simple. It is flat, relatively short, and does not have the obvious โ€œmonster cornerโ€ personality of a place like Road America, Thunderhill, or Sonoma. But that is exactly the trap. PIR asks for precision everywhere. The lap is full of medium-speed commitment, heavy braking moments, curb usage, track-out discipline, and small setup decisions that either build confidence or quietly steal time every lap. If the car is not underneath you, the track exposes it. If the driver is not fully committed, the stopwatch tattles immediately.

Our weekend lineup had a little bit of everything.

Chris Johnson was back in his Spec E46 in Touring 3 for the first time since last July. Gama Aguilar was in the Nissan 370Z, also in Touring 3, continuing the development push from Thunderhill. Beef Wellington brought out his Touring 2 BMW M240iR. And while Ron Tanemura was not technically in one of our cars, he was still part of the broader Racer on Rails driver development program, racing a Spec Racer Ford Gen3 with Flat Out Racing and continuing to work with Tyler through our coaching services.

Different cars. Different goals. Same weekend. Same stopwatch.

Chris Johnson: Back in the Saddle, Then Fully Lit

Chris started the weekend exactly where you might expect after nearly a year away from the car: knocking the dust off.

The Spec E46 was on older tires, Chris was rebuilding rhythm, and the first part of the test day was about getting reconnected with the car. Braking points. Corner entries. Trust. References. The little internal checklist every driver has to rebuild after time away.

By the end of the first test day, though, the fog was clearing. Even as the track got hotter and conditions worsened, Chris started closing back in on his personal best lap times. That was the first sign that the speed had not gone anywhere. It was still there, sitting under the surface, waiting for him to believe it was available again.

The next day, we had one of those conversations that matters more than a shock adjustment or tire pressure change.

Chris was talking through what he was feeling in the car, but underneath the words were a few limiting thoughts. Not excuses. Not weakness. Just the normal stuff drivers tell themselves when confidence is still a lap or two behind capability.

The conversation was about the things we tell ourselves. What we accept as true. What we assume is possible. What we decide is โ€œabout where we areโ€ before the car and the data have actually said that.

Something clicked.

In Saturdayโ€™s race, Chris came alive. He got pulled into a tight battle with a few out-of-class cars that were absolutely flying, and that extra competitive energy did exactly what a good race battle should do. It sharpened him. It pulled his eyes forward. It made him stop driving the idea of the lap and start racing the car in front of him.

The result was a major unlock. Chris knocked roughly a second from his previous bests and started driving with the kind of intent we knew was still there.

Sunday morning, he was determined to prove Saturday was not a one-off. He wanted to build on the confidence instead of simply enjoy the memory of it.

He did.

In Race 2, Chris carried the lessons forward. He cleared the cars he had been battling with on Saturday and found himself racing farther up the field, with new competition and a new target. That is always one of the best signs in driver development: yesterdayโ€™s mountain becomes todayโ€™s baseline.

The wild part? He did all of this while nursing an engine that had given us a scare on Friday. Chris had an over-rev, followed by white smoke out the tailpipe. Jordan kept a close eye on the car for the rest of the weekend, and thankfully it made it through without getting worse.

So yes, Chris had a big weekend on the stopwatch. But the bigger unlock was mental. This was a driver remembering that confidence is not something you wait around to receive. Sometimes you have to go take a bite out of the lap and let the confidence catch up.

Beef Wellington: A Short Weekend, But the Right Call

Beefโ€™s weekend ended earlier than anyone wanted.

The BMW M240iR had a solid shakedown at Pacific Raceways the week before, so we came into Portland expecting to continue learning the car and building momentum. Instead, the car started overheating after only four or five flying laps.

At first, it looked like the usual race-car mystery novel: temperatures okay, then suddenly not okay. The car would run fine, then start building too much coolant pressure and blow through the expansion tank valve.

The team worked through the problem methodically. Cooling system. Pressure behavior. Failure pattern. Repeatability. The ugly little clues all started pointing in the same direction.

Head gasket.

Mega bummer.

That is never the way we want a weekend to end, especially with a new-to-him but still used/junkyard engine. But there is a version of this story that is much worse. We caught it before destroying the whole engine, avoided turning a repair into a full-scale catastrophe, and got the car pointed toward the work needed before June Sprints at Road America later in the month.

Sometimes race weekends are about trophies. Sometimes they are about knowing when to stop digging.

This was the right call. Not fun. Not glamorous. But right.

Ron Tanemura: Expanding the Driving Toolbox

Ronโ€™s Portland weekend had a different purpose.

He was in a Spec Racer Ford Gen3 rental with Flat Out Racing, while continuing to work with Tyler as part of the Racer on Rails coaching program. The goal was not simply to jump in a new car and chase a number. The goal was to expand his driving range.

That matters.

Ron has been intentionally building a broader driving education. Different platforms. Different sensations. Different demands. The SRF3 is a very different animal from a BMW sedan. It is lighter, more direct, more exposed, and less forgiving of half-commitment. It wants clearer inputs. It rewards decisiveness. It asks the driver to be comfortable with the car moving underneath them.

For Ron, the weekend established something important: racing the SRF3 is viable for him. He handled the starts well, showed good awareness, avoided major self-inflicted issues, and built a baseline he can come back to.

The next layer is not secret. It is also not simple.

It is about closing the gap between understanding and execution. Ron has done real work in the sim. He knows a lot of the โ€œrecipeโ€ for the car and track. But the real car adds sensation, consequence, tire feel, traffic, imperfect references, and the pressure of being around other drivers. That gap between knowing and doing is where driver development actually lives.

The coaching takeaway was clear: more commitment, more decisive brake release, clearer throttle discipline, more willingness to let the car rotate, and more assertive racecraft once the race settles in.

That is exactly why this was a valuable weekend. Ron did not just collect laps. He collected a sharper understanding of what the next phase of work needs to be.

And that is the whole point of a driver development plan. Not every weekend is supposed to be a finished product. Some weekends are supposed to reveal the next door.

Gama Aguilar: Engineering the Window

For Gama and the Nissan 370Z, Portland was about building on the lessons from Thunderhill.

At Thunderhill, we had speed, but we were still fighting the car. The Z had pace in flashes, but it was not yet living in a consistent, repeatable window. Under braking and turn-in, the car still had moments where it felt like it was asking for trust without giving enough trust back.

Before Portland, Ian spent a full week digging into the chassis, working through an engineering workbook, checking assumptions, and giving the car the kind of measured attention that separates guessing from development. We are not going to give away every detail of what we found, but the big picture was clear: there was systemic pace hiding in the car.

That was the unlock.

This was not about finding one magic adjustment or chasing a one-lap setup. It was about understanding the car at a deeper level, getting it into a healthier operating window, and creating a foundation we could actually build on across a full weekend.

From there, we reset the approach. The chassis setup moved in a better direction. The car became more predictable. We switched to nitrogen in the tires, including multiple purge cycles to reduce the influence of air and moisture. Then we started fresh on understanding pressure build, temperature behavior, and how to keep the tire in a usable window from the first hard lap to the last.

That became the real work of the weekend.

Not โ€œwhat makes one fast lap?โ€ but โ€œwhat makes the car fast, repeatable, and trustworthy every time we lean on it?โ€

By Friday, the difference was obvious. For the first time ever in the 370Z, we could push the car hard every session and have it respond the same way. The car was no longer giving us a narrow little keyhole of performance. It gave us a window. And once we had a window, we could finally start doing real race-car work.

That is a big deal.

The official Race 1 time cards showed the progress starting to show up on paper, with the #109 370Z quickly moving from a 1:26.946 opening lap into a 1:24.759, then a 1:24.526, then a 1:24.701. More important than the single lap was the shape of the run. The car stayed in the window. The laps stayed usable. The team finally had a platform we could tune instead of survive.

By the race weekend, we were fine-tuning instead of firefighting.

The result was an easy Touring 3 pole, a Saturday T3 win, and then another T3 win on Sunday to complete the weekend sweep.

Saturday was not without drama. At the start, there was unnecessary contact with the STU pole sitter that could have ended the race before it properly got going. Thankfully, the Apex forged wheel took an absurd hit and somehow held on. The car survived, the tire held, and we were able to finish.

On Sunday, we replaced the damaged wheel and tire, put our heads down, and went for a maximum race-pace push.

That was the most encouraging part of the weekend. Not just winning. Not just getting through the races. But seeing that the car had pace in conditions that were not perfect. The overcast morning cloud cover had burned off by the time our Sunday race started, the track was warmer, and the car still had the ability to push toward the kind of pace we have seen from some of the strongest Touring 3 drivers at this event in prior years.

That is the good stuff.

The kind of weekend where the notebook matters as much as the trophy.

The Team Behind the Weekend

Like most race weekends, Portland had its share of curveballs.

Jordanโ€™s personal car broke down on the way to Portland. Beefโ€™s M240iR tried to turn Friday into a cooling system crime scene. Chrisโ€™s Spec E46 had to be monitored all weekend after an over-rev and smoke. The Z needed continued tuning and then a wheel/tire change after race contact.

None of that is unusual in racing. That is the job.

What mattered was how the team responded.

Ianโ€™s engineering work before the event gave the Z a new foundation. Jordan kept Chrisโ€™s car alive and monitored. Tyler continued guiding drivers through both technical and mental development. The crew absorbed the chaos, kept working the problems, and moved the weekend forward.

That is what we want Racer on Rails to be.

Not just a shop that brings cars to the track. A team that develops cars, develops drivers, solves problems, and helps people leave the weekend with better tools than they arrived with.

Portland gave us a lot.

A Touring 3 weekend sweep for the 370Z. A major mental unlock for Chris. A hard but smart diagnostic call on Beefโ€™s BMW. A valuable SRF3 baseline for Ron. A stronger engineering process for the team. And a reminder that race weekends are rarely clean, but they can still be deeply productive.

We left Portland feeling like the whole program moved forward.

Goals. Smiles. Memories. LFG.

SCCA US Majors Tour – Thunderhill 2026 – The Last Stop South

Racer on Rails paddock'ed at Thunderhill Raceway Park

In late April, we wrapped up the final stop of our early-season West Coast racing trip with the 2026 SCCA U.S. Majors Tour at Thunderhill Raceway Park.

This trip started in February at Buttonwillowโ€™s new โ€œThe Circuitโ€ layout, continued through a NASA NorCal weekend at Sonoma Raceway, and finished at Thunderhill before the cars, hauler, and team made the long drive back to the Pacific Northwest.

For anyone newer to club racing, the SCCA U.S. Majors Tour is one of the national-level competition paths within the Sports Car Club of America. It brings together strong regional and national drivers, gives racers a chance to measure themselves against deeper fields, and, for many drivers, forms part of the path toward the SCCA National Championship Runoffs.

Thunderhill is always a fun place to end a trip like this. It has elevation, fast commitment corners, technical braking zones, and enough rhythm changes to keep a driver honest. For this event, we ran the Crows Nest configuration, which adds its own personality to the lap and rewards drivers who can stay patient, committed, and precise.

For Racer on Rails, this weekend had two main drivers:

Gama Aguilar-Gamez in the No. 109 Nissan 370Z, competing in Touring 3

Ron Tanemura in his BMW Spec E46, competing in Touring 3 and STU

On paper, it was another race weekend. In reality, it was exactly the kind of weekend that shows why we love this sport so much. There were clear goals, real progress, hard-earned smiles, and a few memories that will probably get retold in the paddock for a long time.

Why We Were There

Every driver came into Thunderhill with a different mission.

For Gama, the weekend was an important step in the 2026 Runoffs journey. To qualify for the SCCA National Championship Runoffs, drivers need to complete the required number of race weekends and race finishes. After completing two races earlier in the season, Thunderhill became a critical opportunity to add two more finishes and move much closer to locking in the qualification path.

Ron Tanemura never stops looking for opportunity!

But the weekend was not just about checking a box.

The 370Z is still a car we are actively developing. It has shown strong pace, but like most serious race cars, especially one being pushed toward national competitiveness, the work is never really finished. Reliability, braking behavior, tire temperature, chassis balance, setup range, and driver confidence all remain part of the larger development puzzle.

For Ron, the goal was different but just as important.

Ronโ€™s bigger mission this year is driver development. Not just getting faster in one car, at one track, in one situation, but becoming more adaptable, more trusted, and more complete as a driver.

A big part of that is variety. Different tracks. Different race groups. Different cars around him. Different levels of pressure. The long-term target is for him to be the kind of driver who can step into different racing environments, learn quickly, run cleanly, stay close enough on pace, and be trusted by the people around him.

That does not happen by accident.

It happens by putting yourself in new situations, then doing the work to understand them. It happens by learning how to drive a car when it moves around underneath you. It happens by getting comfortable being uncomfortable.

Thunderhill gave Ron exactly that kind of opportunity.

Ronโ€™s Weekend: Raising the Baseline

Ron came into Thunderhill with a very clear goal: build on last year, get more comfortable with the car moving underneath him, and leave with a higher baseline as a driver.

That is one of the things we love about working with Ron. He is not just chasing a result. He is actively working on his craft. He pays attention to what the car is doing, what he is doing, and where the next layer of performance might be hiding.

Thunderhill gave him a perfect environment for that.

Last year, Ronโ€™s best lap at Thunderhill was a 2:06.24. This year, he came close with a 2:06.46. On paper, that means he did not beat his previous personal best. But the timing sheet does not tell the full story.

The bigger win was consistency.

Last year, Ron had one lap in the 2:06 range, one lap in the low 2:07 range, and a handful of laps in the 2:08s. This year, he had five laps in the 2:06s, eight laps in the 2:07s, and seventeen laps in the 2:08s.

That matters.

A single fast lap is fun. A higher baseline is progress.

Ronโ€™s own takeaway from the weekend was that he did not feel quite as โ€œon itโ€ as he did at Sonoma, but he was close enough to feel like his pace is becoming more real and more repeatable. That is exactly the kind of step we want to see from a developing driver.

The biggest learning was around car control.

Post session – getting that Chequered flag for Ron!

When Ron was faster, the car was moving. It was rotating. He was catching it, correcting it, and working with it instead of waiting for the car to feel perfectly settled. During Friday testing, especially in the later sessions, he started getting more comfortable with that feeling. The next challenge is learning how to access that level of commitment earlier in a session, instead of needing several laps to build into it.

That became one of his biggest themes from the weekend: push earlier, trust the car sooner, and learn to drive closer to the limit on demand.

Saturday showed that progress.

In his first Touring 3 qualifying session, Ron was quick and consistent, including a run of laps in the 2:06s before the session ended. Later, in his second qualifying session, he was fast immediately after the restart, showing that the pace was starting to become easier to access.

The races gave him a different kind of experience.

In Touring 3, Ron finished second in class. It was a solid result, but he did not have as much direct class competition around him as he would have liked. At Sonoma, he had more sustained battles, and Thunderhill was a little quieter in that regard.

But the weekend still gave him valuable race craft notes.

He worked on starts. He worked on positioning. He got reminders about following closer before the green, not over-defending Turn 1 when there is an opportunity to open the gap, and using commitment through fast corners to set up passing opportunities later in the lap.

Then Sunday threw the team a curveball.

During Touring 3 qualifying, Ron quickly realized he had lost fourth gear. The transmission needed to be replaced, and the clock was not exactly being generous.

Thankfully, we had a spare transmission available.

The team looked at the schedule and knew it was going to be tight, but there was still a chance to get Ron back out for the STU race later that afternoon.

There was also something special waiting at the end.

At SCCA Majors events, class winners often receive more than a trophy. This event was hosted by the San Francisco Region, and the class-win flags were a cool keepsake from the weekend.

So we made the call: letโ€™s get Ron that flag.

The team jumped on the transmission swap, got the car buttoned up, warmed up, checked over, and ready. Ron made it to the race.

And he delivered.

He finished third overall in Group 2, won STU, and brought home the flag.

But the real story was not just the flag. It was the full arc of the weekend: clear goals, honest self-assessment, measurable progress, a mechanical setback, a team thrash, and one more chance to go race.

That is the kind of weekend that builds a driver.

Gamaโ€™s Weekend: Runoffs Progress and More 370Z Development

For Gama, Thunderhill was about two things: continuing the Runoffs qualification path and continuing to develop the No. 109 Nissan 370Z into a nationally competitive Touring 3 car.

This was only the second full race weekend of the season for the Z, and we came in with some important new learning.

Before the event, Tyler spent time with our partners at Motion Control Suspension to better understand the internal behavior, adjustment range, and service considerations of our three-way dampers with external reservoirs. The details matter, and we came away with more tools in our toolbelt that have helped us start fine tuning the carโ€™s behavior.

For a car like the 370Z, which has shown both pace and some sensitivity around braking behavior and tire temperature management, that kind of learning matters. We have been trying to understand how to make the car more compliant, more consistent, and easier to extract speed from over a full race distance.

The goal was not to find one magic adjustment. Race cars rarely work that way.

The goal was to understand the platform better, continue chipping away at reliability concerns, give the driver a car that communicates more clearly, and keep moving the program forward with discipline.

That is the unglamorous part of race car development. It is not always fireworks. Sometimes it is pressure checks, damper notes, tire readings, brake feel, driver feedback, and the quiet little decisions that add up to real progress.

Thunderhill gave us more of that.

On Saturday, Gama finished fifth overall in Group 1 and first in Touring 3, with a best lap of 2:02.789. That result mattered for the points and the Runoffs path, but it also showed that the 370Z had real speed in the class.

On Sunday, the priority was clear: finish the race, keep stacking Runoffs qualification progress, and bring the car home. Gama finished fourth overall and again first in Touring 3, adding another strong finish to the season.

That's another P1 sweep of a race weekend for Ian, Gama, and the Nissan 370z in SCCA Touring 3

Just as importantly, the weekend helped validate some of the direction we are taking with the chassis. The car became easier to work with, more predictable, and more useful as a development platform.

For Gamaโ€™s season, the biggest objective was to continue stacking the race finishes needed for Runoffs qualification. In that sense, the weekend did exactly what it needed to do.

For the car, it gave us more data.

It’s not all roses and daisies when chasing speed. Sometimes you find yourself in the grass…

For the driver, it gave more confidence.

For the team, it gave another reminder that the path to national-level competitiveness is built one weekend, one session, and one decision at a time.

The Bigger Picture

The easy version of a race recap is to talk about qualifying positions, lap times, race results, and trophies.

Those things matter. We care about them. We work hard for them.

But the best weekends usually have another layer.

Ronโ€™s weekend was a perfect example. He hit the goals he came in with, but still left wanting more. That is a good place to be. He raised his baseline, got more comfortable with the car moving, built more race craft notes, identified where the next step is, and still came home with a class win flag after the team thrashed to get him back on track.

Gamaโ€™s weekend was different, but connected. The 370Z program took another step forward, the Runoffs path became more achievable, and we continued learning how to get more out of the platform without losing sight of reliability and drivability.

That is the heart of what Racer on Rails is becoming.

Yes, we prepare race cars. Yes, we support race weekends. Yes, we care deeply about setup, reliability, data, execution, and all the thousand little details that make a race car work.

But ultimately, we are here to help drivers become better drivers.

Sometimes that means building a faster car. Sometimes that means making a car easier to trust. Sometimes that means helping a driver understand what they are feeling. Sometimes that means creating the right environment for a driver to stretch, learn, and come back wanting more.

We want to help people set goals that matter to them, whether that is winning a national championship, earning a Runoffs invite, becoming more comfortable with car control, developing race craft, or simply leaving the track knowing they took a real step forward.

That is why weekends like Thunderhill matter.

P1 both races in SCCA Touring 3 and collecting some hardware before the weather rolled in!

The cars came back north to the Pacific Northwest with more miles on them, more notes in the book, and a few more stories for the paddock. For us, it felt like the right ending to the first chapter of the season.

And for our drivers, it was another reminder that progress in racing rarely arrives as one giant leap.

Most of the time, it shows up as one better corner, one cleaner race, one smarter adjustment, one hard-earned finish, and one flag you almost did not make it back on track to win.

Porsche Cayman GT4 Clubsport Build Overview

(2020 718 GT4 Clubsport โ€“ Track Day Edition)

If youโ€™ve followed Racer on Rails for a while, you already know our philosophy: take great cars, make them better, and then drive the hell out of them. This 2020 Porsche Cayman GT4 Clubsport Track Day Edition is the perfect example โ€” a factory-built Porsche Motorsports car with real pedigree and a second life that spans endurance racing, time attack, and driver development.

Before we go deeper, itโ€™s important to understand which Clubsport variant this is, because Porsche built several versions:


718 Cayman GT4 Clubsport Variants

Track Day Edition (This Car)

  • Designed for private owners and track day use
  • Same 425 hp 3.8L flat-six as Comp version
  • Lighter-duty fuel system
  • No air-jack system (but provisions exist)
  • Not homologated for GT4 racing

Competition Version (Not This Car)

  • Fully homologated for GT4 racing
  • Air-jack system included
  • Larger motorsport fuel cell
  • Endurance switches & safety electronics
  • Homologation restricts power/aero changes
  • Carbon and natural fiber material body panels

Newer 718 Cayman GT4 RS Clubsport

  • 4.0L RS-based platform
  • More power, higher RPM ceiling
  • Improved aero and suspension
  • The current model used in IMSA/SRO GT4
  • Much closer to a โ€œmini Cup Carโ€

Our car โ€” the Track Day Edition โ€” gives us the freedom to pursue more aero, more setup range, and more developmental headroom than the rules-restricted Competition version.


Where This GT4 Clubsport Came From

Photos of the car from its Ann Doherty era after arriving at RoR.

This GT4 Clubsport began its life with Ann Doherty, who ran it competitively in SCCA T1 and GT2 before upgrading to a 991.2 GT3 Cup Car.

Because the car came from Ann, we gained two major benefits:

  1. It had been maintained at a true professional standard.
  2. It had already proven itself at a national competition level.

When she moved to the Cup Car, we took ownership of the GT4 and immediately put it to work.


What We Used It For

1. Endurance Racing (2024)

Bombing down Turn 5 at Road America with World Racing League

The first chapter of this carโ€™s life with us was national-level endurance racing:

  • WRL Road America โ€” April 2024
    Our first outing. Strong pace, great aero learning, and flawless reliability.
  • ICSCC Cascade 8 Hours of Portland โ€” October 2024
    A full-day grind that gave us massive data on tire wear, pit strategy, and aero balance.

The car was consistent, predictable, and incredibly reliable โ€” exactly what you want in an endurance platform.


2. OnGrid Time Attack (2025)

With the Dundon Valkyrie aero package installed, the car moved into OnGrid GT+ and instantly became a serious contender.

Huge downforce. Big mid-corner speed. Better braking stability. It was a transformation.

3. Driver Development & Testing Tool

This GT4 became one of our strongest tools for:

  • Advanced driver coaching
  • Back-to-back setup testing
  • Tire comparisons
  • Driver development beyond Spec E46, T3, and regional touring classes

Turnkey speed. Zero drama. Endless data.

June 2023 โ€” Homologated GT4 Aero @ Road America

  • Hoosier A7 (sprint tire)
  • Full GT4 power
  • Lap: 2:25.6

April 2024 โ€” Dundon Aero @ Road America

  • Yokohama A052 (endurance tire)
  • WRL power restrictions (ยพ intake blocked)
  • Full endurance fuel levels
  • Laps: Low 2:24s โ€” consistent

Less power.
Heavier car.
Slower tire.
Faster laps.

Conclusion:

The aero works. It transforms the platform. Check out this video comparison of the Dundon vs Manthay aero on the faster Cayman RS GT4.

SCCA Hoosier Super Tour – Buttonwillow The Circuit

High Performance Race Cars on Track at Racer on Rails.

The Setting: Why Buttonwillow Matters

The opening round of our 2026 SCCA season brought us to Buttonwillow Raceway Park for the first SCCA Hoosier Super Tour of the year, February 21 – 22, 2026.

We raced on The Circuit configuration โ€” Buttonwillowโ€™s newer layout thatโ€™s been operating for over a year now and we were here last year, for the very first competition race weekend and event ever held at the new track. Ron competed here twice last season. For the rest of the team, weโ€™ve logged time here supporting customers. But this was our first time bringing the Nissan 370Z to this configuration in race trim.

Touring 3 remains one of the most competitive, tightly regulated classes in SCCA road racing. The cars are production-based, but execution is everything. Small setup shifts matter. Tire management matters. Driver discipline matters.

Buttonwillowโ€™s The Circuit layout also brings a very different technical personality compared to the original โ€œButtonwillow 13CWโ€ configuration that many West Coast racers grew up on. Traditional Buttonwillow rewards aggression, commitment over bumps, and managing long-flowing corner sequences with a little bit of chaos built into the surface and sightlines. The Circuit, by comparison, feels more modern and much more precise. The pavement quality is smoother, the transitions are faster, and the corners tend to stack technical decisions on top of each other.

Sun is setting at Buttonwillow The Circuit – when the sun goes down, the air and track temps drop fast in February.

Several sections reward sacrificing entry speed to maximize minimum corner speed and throttle commitment on exit, while other complexes punish even tiny balance mistakes with lost momentum that carries for multiple corners afterward. Itโ€™s also a track where aero drag, mechanical grip, brake release timing, and tire temperature management all become more interconnected than people initially expect. A car that feels โ€œpretty goodโ€ for one lap can quickly become difficult over a race run if the balance isnโ€™t properly managed. In many ways, The Circuit feels less like old-school club racing Buttonwillow and more like a purpose-built modern technical circuit that rewards disciplined engineering and adaptable drivers.

At just over 2.5 miles in length, The Circuit combines roughly two dozen corners and transitional elements ranging from slow, technical rotation zones to fast, committed sweepers that reward precision and patience. The layout constantly shifts between decreasing-radius corners, long loaded exits, quick direction changes, and several areas where throttle timing matters more than outright bravery. For Touring 3 cars, gearing becomes especially important because many sections sit right on the edge between carrying momentum in a taller gear versus risking upsetting the platform with an additional shift.

The track surface itself is relatively smooth compared to the original Buttonwillow layouts, but the environment still plays a huge role in grip evolution. Located in Californiaโ€™s Central Valley, the circuit is frequently impacted by wind carrying fine dust and sand onto the racing line, while dramatic temperature swings between cold mornings and warmer afternoons can significantly change tire behavior and overall balance throughout a race weekend.

Buttonwillowโ€™s Circuit layout rewards rhythm and precision. There arenโ€™t many places to hide mistakes. Itโ€™s a track that exposes imbalance โ€” mechanical or mental.

That made it the perfect place to start the year.


The Mindset: Process Over Outcome

Coming into the weekend, our objectives were clear:

  • Establish a stable performance baseline for the 370Z
  • Continue refining Ronโ€™s throttle application and adaptability
  • Validate our tire pressure management process
  • Execute cleanly as a team

We intentionally chose to run lightly used tires instead of bolting on fresh rubber. Not to handicap ourselves, but to operate with discipline and long-term planning in mind.

For Ron, this season is about expanding his toolbox. Heโ€™s put in serious off-season work โ€” simulator training, Porsche ice driving, DirtFish advanced programs โ€” all focused on becoming more adaptable and decisive with inputs.

Ron Tanemura carving corners in his Touring 3 BMW Spec E46

For the team, this season is about raising our operational standard. When something breaks, we fix it properly. When development is needed, we create bandwidth for it.

No chasing. No scrambling.

Build it right.


The Weekend Story

The Journey South

Jordan and Ian drove the truck down through snow over the Oregon passes. Enough weather to keep things interesting, but they maintained traction and avoided chains. We arrived in California clean and on schedule.

That matters more than people think.


Testing: Cold Mornings, Steady Gains

Thursday brought cold temps and passing showers. Ron used early sessions to reacquaint himself with slip and rotation. By Friday he was back at 2:00.0 pace โ€” only tenths off his personal best from last year at this track.

The 370Z test sessions were structured and deliberate. Controlled three-lap tire validation runs. Minor line adjustments through Turn 3, 5, 8, and 10. By Friday afternoon, we were consistently in the 1:56s with room left in the data.

The car was stable. Predictable. Repeatable.

Baseline established.


Mechanical Curveballs

Late Friday we discovered the Nissanโ€™s clutch was nearing end-of-life.

Ian working his tail and back off, getting the clutch replaced on the Touring 3 Nissan 370z Nismo

Saturday morning became paddock surgery.

Transmission out.
Clutch replaced.
Qualifying missed.

Ronโ€™s clutch was also right at a seasonโ€™s worth of cycles, so we proactively replaced his as well. Two clutch jobs in one weekend.

It wasnโ€™t glamorous work, but it was done calmly and correctly.

Thatโ€™s culture.


Saturday Race: From the Back

Starting P28 overall after missing qualifying, the only direction was forward.

The opening lap was tight but clean. From there, it was controlled aggression and patience.

Twenty-two passes in twenty-five minutes.

Finished:

  • P6 overall
  • P2 in Touring 3

Fastest lap of the race would have placed us P2 on the grid for Sunday.

Sunday: Clean Execution

Sunday qualifying required careful temperature management after diagnosing a cooling fan issue. Despite traffic on both flying laps:

  • P2 in class
  • P4 overall
Gama and Ron making laps and loving every braking zone at Buttonwillow The Circuit

The race start was steady. The leaders stretched a gap as the rear tires began to show their age around lap five. Turn 1 required finesse and progressive inputs to manage increasing rotation.

Post-race inspection confirmed tire edge wear consistent with heavy cycling.

Final result:

  • P2 in class

Not quite the fight for P1 we would have liked, but an honest and disciplined run.

Starting the Race 2 from the front of the grid but not enough pace to truly challenge for P1.

Ron: Double Podium Weekend

Ron started P3 in class Sunday and battled closely with Spec MX-5 cars running in STL for additional seat time. Those cars were quick and the racing was tight.

There was side-to-side contact exiting Turn 3 that pushed him wide, but he stayed composed and fought back.

He finished:

  • P3 in class
  • Double podium weekend

Both races resulted in an all-Pacific Northwest podium sweep, with Scotty B White completing the trio.

Ron left energized and sharper. More sensitive to the car. More decisive on throttle. Clear on what to improve next.

Thatโ€™s exactly what this weekend was for.

What We Take With Us

We worked through:

  • Snow-covered travel
  • Two clutch replacements
  • Cooling fan troubleshooting
  • Traffic-filled qualifying sessions
  • Tire degradation management

None of it materially impacted our results.

More importantly, the 370Z now has a clear and repeatable performance baseline. The upgraded big brake kit performed flawlessly. The car responds predictably to setup changes.

That’s a full PNW podium sweep for the Buttonwillow Hoosier Super Tour

We leave Buttonwillow not chasing something unknown โ€” but building on something understood.

Thatโ€™s the difference.

Goals were pursued with discipline.
Smiles were earned in the paddock and at dinner tables.
Memories were made in the moments that required composure.

Next stop: Sonoma Raceway with NASA.

The foundation is set.
Now we build.

SCCA Touring 3 Nissan Nismo 370Z #109 โ€” Build Overview

Introduction

Every race car has a story, and our goal with these build overviews is to pull back the curtain a bit and share the why behind each one. Not just the spec list or the shiny parts bolted on, but the decisions that shaped the build, the lessons we learned the hard way, how the car performs today, and where weโ€™re taking it next. Think of this as a guided walk through the full journey โ€” the good, the bad, the breakthroughs โ€” so that whether youโ€™re dreaming up your first build, refining a current project, or planning something wild for the future, youโ€™ve got real-world insight to draw from. And hey, if any of this sparks ideas or youโ€™re curious about building a similar car, weโ€™re always happy to talk shop and help you get pointed in the right direction.

Gama shaking down and testing things to figure out the brakes in his 2011 Nissan Nismo 370Z in SCCA Touring 3 Class

How We Ended Up in a Nissan 370Z for Touring 3

Our path to campaigning a Nismo Nissan 370Z in SCCA Touring 3 didnโ€™t start with a Z-car at all โ€” it started with a fleet of BMW Spec E46s and a once-in-a-lifetime opportunity.

Back in 2021, the SCCA Runoffs were being held at the Indianapolis Motor Speedway. Thatโ€™s bucket-list territory. There was absolutely no way we were going to miss the chance to race at Indy, so we brought our Spec E46 drivers and cars and dove into T3 with both feet.

That first year was awesome. The SE46 was decently competitive and, with a 2,950-lb minimum weight in Touring 3 (vs. 2,850 in the spec class), we still felt like the platform had room to grow. We were optimistic.

Even a hurricane couldn’t slow down the field enough to make a Spec E46 competitive at big tracks like VIR

But 2022 at VIR changed everything.

VIR is the polar opposite of Indy when what matters most is top-end speed. And in T3, you simply cannot hide from that reality. While the front-running cars were consistently touching 138โ€“140 mph top speeds, our Spec E46s were essentially tapped at 136 mph, and in reality at VIR, we were barely seeing 132 mph with a draft.

So even if the chassis could somehow theoretically match the lap times, the racing wasnโ€™t viable. It was a harsh reality check, but a necessary one.

Time for a Change

After the 2022 Runoffs, we evaluated realistic alternatives:

  • BMW Z4 M Coupe
  • Nissan 370Z

We also had a 2010 Porsche Cayman PDK ready to build, but the timeline and development curve didnโ€™t match our Runoffs schedule.

The turning point came when a proven, nationally competitive T3 370Z changed hands and landed with our friend Chris Hart. Suddenly, we had access to race-winning data and real experience. Combined with the 370Zโ€™s double-wishbone geometry โ€” perfect under T3โ€™s 3.5-degree camber limit โ€” the choice became clear.


Buying the Car โ€” A True Nismo

In mid-2023, we bought a 2011 Nissan 370Z Nismo โ€” a true, original-owner Nismo.

Because the shop was at max capacity, the entire initial teardown happened in the driveway. Full interior strip, seam sealer removal, weight reduction โ€” everything. We delivered a perfect rolling chassis to Fabtek for a cage that matched Chris’s championship-proven design.

Cage & Safety Fabrication

Once Fabtek completed the cage, we resprayed the interior in OEM Nismo red and began the race against time to assemble the car before the 2023 Runoffs at VIR.


2023 Runoffs โ€” The ABS Reality Check

We made it to VIRโ€ฆ but the first test day exposed the 370Zโ€™s biggest flaw: its factory ABS logic.

We experienced full-on ICE mode, where the ABS system dramatically reduces braking pressure unpredictably. It ended our Runoffs before the weekend truly began โ€” but thank God, the car and driver were safe.

Post-Runoffs: Fixing the Brakes

That failure changed everything. We went deep into:

  • pad compounds
  • rotor configurations
  • wheel-speed ratios
  • heat management
  • master cylinder behavior
  • ABS trigger logic

We broke things. Tested everything. Logged everything. Even pushed for rule adjustments when needed.

And now? The brakes are one of the absolute strengths of the car.

June Sprints at Road America โ€“ A Weekend of Grit, Growth, and Podiums

Turn 1 at the start of the Touring 3 race at SCCA Chicago Region June Sprints race!

A few weeks ago, we were at Road America for one of the most iconic events in club racing: the SCCA June Sprints.

There are tracksโ€”and then thereโ€™s Road America. Nestled in the rolling hills of Elkhart Lake, Wisconsin, Road America is one of the most iconic and demanding circuits in North America. At 4.048 miles, itโ€™s one of the longest permanent road courses in the country, with 14 turns that blend technical precision with full-send bravery. Corners like the Kink, the Carousel, and Canada Corner donโ€™t just test your carโ€”they test your commitment. Turn 5 is the โ€œslowestโ€ min-speed corner at a target min-speed of 55-60 mph, depending on the car! That is the โ€œslowestโ€ with the rest of the corners having target min-speed of 65, 80, 90 and 110 mph. ????

And then thereโ€™s the June Sprintsโ€”a race weekend steeped in history. Since 1956, the June Sprints have stood as a cornerstone of American amateur road racing. Itโ€™s a proving ground for national champions and future pros, where every lap carries the weight of decades of racing tradition.

But what truly sets this weekend apart is Elkhart Lake itself. This little town breathes motorsport. Historic restaurants like Siebkens and The Osthoff are filled with old racing photos and stories, and the street signs and commemorative plaques around town proudly mark the original road course from the 1950s, when racing took place on public roads. Itโ€™s a place where history isnโ€™t just rememberedโ€”itโ€™s woven into the landscape.

Just down the road isย RealTime Racing HQ, a name familiar to any longtime fan of World Challenge or Honda racing, SO COOL! And everywhere you look during June Sprints weekend, the town is buzzing with performance carsโ€”from vintage Porsches to modern GT4 machines. Itโ€™s aย car loverโ€™s paradise, and for racers like us, itโ€™s nothing short of heaven.



Big Brains, Big Gains โ€“ Engineering First

Before a single lap was turned, Tyler Campbell was already deep in the work: suspension geometry, brake data, tire modelingโ€”he put in the kind of effort that sets great teams apart. We showed up with one of the most dialed-in testing plans weโ€™ve ever run, and it paid off.

We donโ€™t show up to look cool (or at least we think we try to look cool but look like a bunch of racing and track nerds! ????) and bench race. Weโ€™re here to science the crap out of our race cars and racing!

Wednesday & Thursday โ€“ Building the Foundation

We rolled in Tuesday night with storms on the radar. Wednesday morning was still wet, but once the track dried, we got to work. We missed the first test session due to the wet track and expected dry conditions through the rest of the race week, but kicked off our structured setup plan with back-to-back sessions focused on testing our hypotheses.

I ran our Spec E46, not because we expected to win overall, but because it gave us a solid, familiar platform to test against elite-level competition (and the Touring 3 Nissan 370Z needed another heart transplant, weโ€™ll get into that more in a future post).

Every change delivered something newโ€”every lap taught us something valuable.

Thursday, we mounted fresh tires and saw a measurable step forward. All signs pointed toward progress, and it gave us confidence heading into the official sessions.


Friday โ€“ Contact, Recovery, and Grit

Morning practice started off wellโ€ฆ until it didnโ€™t.

Dave Orem got dive-bombed in Turn 1. The hit spun him, left him stalled, and another carโ€”unable to avoid himโ€”collected the Z4M hard.

Thankfully, Dave was okay. And thanks to an incredible community, we pulled off a minor miracle: sourcing every part needed to get him back on track.

Shoutout to Trevor and Wyatt at Motion Control Suspension for building a replacement MCS shock on short notice and getting it to us overnight.


Friday Qualifying โ€“ Almost There

Meanwhile, I was out for qualifying in the E46. Brand new tires. Low Super Tour points meant I was gridded at the back of the T3 field. But we knew we had pace.

Twice, I was on flying laps that wouldโ€™ve moved me to P2 or P3โ€”both times caught in traffic at the carousel and kink. Absolutely destroyed those laps.

We finished the day P4. Not ideal, but we knew more was coming.


Saturday โ€“ Reset & Rebound

With Daveโ€™s car repaired, he jumped back in for qualifying.

โ€œI didnโ€™t think about the car at all. I was able to focus on finding space and putting down lap times.โ€

Exactly what you want to hear after an incident. He wasnโ€™t fully back to pace yet but showed strong progress.

For me, Saturday qualifying locked in P4. Solid lap. Solid position. Not a perfect lap, but enough to put us in contention for Sunday.


Sunday โ€“ Race Day

Daveโ€™s Race

Sunday morning, Dave started deep in mixed-class traffic. Lost a few spots at the start, but once the field spread out, he got to work.

Lap by lap, he found rhythm, overtook competitors, and with just a few laps to goโ€”reset his personal best lap time.

He finished P5 in Touring 3, proud of the recovery but wishing he had the two missed sessions to build more momentum.

Great start, dicing for P2 and P3 early. Lap 2 brought a jam up into Turn 3 behind a slowing T2 car. Another T3 car got through; I had to wait. That 3โ€“4 second gap to P3 took several laps to close.

Then it happened.

P3 (another Spec E46) dropped a tire into the dirt under braking. Big wiggle. Lost momentum. I got in the draft, faked right, popped left, held side draft as we bent leftโ€”and completed the pass into Turn 5 with a wheel in or nibbling at the grass.

From there? Hit marks. Build gap. Donโ€™t look back.

By the final laps, the lead over P4 was 30+ seconds. P2 and P1 had gotten through the local yellow before me, and that ultimately determined the gap. I brought it home in P3.

What Racing Teaches Us

One of the things I love most about racing is how often weโ€™re proven wrongโ€”and how thatโ€™s a good thing. What we โ€œknowโ€ is always based on the best data and insight weโ€™ve gathered up to that point. The goal isnโ€™t to be right all the timeโ€”itโ€™s to stay curious, stay humble, and keep growing.

And thatโ€™s what we did at Road America.


Letโ€™s Build Your Path in Motorsports

If the way we raceโ€”the way we prepare, develop, and pursue excellenceโ€”resonates with you, letโ€™s talk.

Weโ€™re not just about cars. Weโ€™re about people, progress, and purpose.
And weโ€™d love to help you chase your motorsport goals.

MEGA Weekend at The Circuit @ Buttonwillow Raceway Park!

Double Podium and the top step for Dave and Ron!

The 2025 Racer on Rails SCCA racing program kicked off in California at The Circuit, the newly built racecourse at Buttonwillow Raceway Park. This was a weekend of firstsโ€”not just for us, but for the entire everyone, as we took part in the first-ever sanctioned race on the new track! 

Everything about The Circuit was new; new track, new tire brand for both slick and wet setups, new coaching program, new competitors, and new adventures. Our drivers and crew had plenty to learn, and we approached the weekend with specific goals and a detailed game plan for each driver. With two days of testing, racing, and strategy calls, the team made incredible strides, achieving personal bests, podiums, and a 1-2 finish in Race 2 on Sunday. 

Meet the teamย 

Ron and Reid in impound, post-session

Ron Tanemura & Car Chief Reid Morris 

#63 SE46 BMW 330i | SCCA Class – Touring 3 (T3) 

  • 2024 ICSCC SPM Class Champion ???? 
  • First-ever SCCA U.S. Majors Tour event 
  • Entering Racer on Railsโ€™ SCCA Competition Program 

Ron has been racing with Racer on Rails in the Pacific Northwest for a few years, but this was his first-ever SCCA Majors Tour race and his fist season working full time with Reid. After earning the 2024 ICSCC SPM Class Championship, he stepped up to challenge himself further in national competition. This weekend was a big new challenge โ€”a brand-new track, new competitors, and a stomach bug. But Ron came ready to party, and nothing was stopping him. 

Rene getting Dave strapped in for race 1.

David Orem & Car Chief Rene Perez 

#6 BMW Z4 M Coupรฉ | SCCA Class – Touring 3 (T3) 

  • Touring 3 podium finisher 
  • Has mastered Heel-Toe Shifting during the off-season 
  • Goal-Oriented approach 

Dave returns to our SCCA program looking to reach the sharp end of the T3 field. With a fresh rebuild on his Z4 M Coupรฉ including a stunning new vinyl wrap, Dave arrives fit, focused and determined.  The pairing showed steady progression all weekend, culminating in a checked bag fee on the flight home for a bag containing new hardware. 

Simon’s sweet Porsche GT3 Cup Car in post race impound

Simon Asselin & Car Chief Jordan Allen (“The Doctor”) 

#81 Porsche Motorsport 991.2 GT3 Cup | SCCA Class – GT2 

  • 2023 SCCA Touring 3 Points Champion 
  • Racing in one of the most competitive SCCA grids, GT2 
  • Third-fastest GT2 lap time of the weekend 

Simon and Jordan have been working together for multiple seasons, and after a strong debut year in GT2 last season, they returned to challenge for the podium in 2025. This series offers the challenge of multi-class race groups including a large Spec Corvette field, Simonโ€™s consistency and pace kept him at the front of the GT2 field, all while navigating the pack of slower class cars. 

Friday Test Day โ€“ Cold Starts and First Impressions 

We arrived at The Circuit before sunrise on Friday, greeted by well-below-freezing temperatures and frost covering everythingโ€”cars, buildings, and the track. Luckily, the team had already set up the night before, allowing us to jump straight into unloading and prepping for the 9:00โ€“9:30 AM test session. 

By the time the first cars hit the track, the frost had lifted, and the sun was breaking through. This was the first real-world drive for any of our drivers on the new layout, making it a crucial day of adaptation

Driver Progress: 

  • Simon Asselin: Locked in the 1:45 range, pushing near the expected top pace. 
  • Dave Orem: Improved into the 2:06 range, showing steady progress. 
  • Ron Tanemura: Battling fatigue, made strides before sitting out the final session to recover. 

With simulator prep translating well to reality, we ended the day confident in the teamโ€™s progress heading into Saturday. 

Saturday โ€“ Practice, Qualifying & Race 1 

Saturday morning started with feedback sheets from Tyler Campbell, analyzing Fridayโ€™s data to pinpoint one or two focus areas for each driver. The goal: apply the learnings immediately in the morning practice and first qualifying session. 

Ron had an early spin during morning practice, leading to the discovery of a failing battery. Missing part of practice, he rebounded well in qualifying.  Dave executed perfectly, shaving seconds off his previous best lap.   

Simon struggled with traffic in qualifying but still secures a start from row 2. 

Saturday Qualifying Results: 

  • Touring 3: Dave P2, Ron P5 
  • GT2: Simon P3 

Saturday Race 1 โ€“ Making History 

T3 Race 1: 

The first-ever sanctioned race on The Circuit was a split start, with Spec MX-5 Cup cars leading and Touring 3 cars behind.  The race brings improving track conditions and with the help of lots of data and video analysis, defined goals and executing on our action plans, Dave charges to a 2nd place finish, while Ron continues to improve despite still recovering from food poisoning, finishing the race in 4th

GT2 Race 1: 

Better track conditions and cool air set the stage for Race 1 in GT2.  Simon has some great racing of his own, as he trades positions with a few GT2 cars before finishing the race in 4th place.    

Sunday โ€“  Morning Qualifying, Wet Track, Big Decisions 

Early morning rain rolls in leaving us with a damp but drying track.  Our turn is up for T3 qualifying and mixed conditions still exist.  We are forced to make a strategy call on tires, so we go to Jordo at our Weather Desk.  The decision is slicks, and it pays off as the track conditions improve and we begin finding speed in quali #2. 

Sunday Qualifying Results: 

  • Touring 3: Dave P2, Ron P3 
  • GT2: Simon P3 

Touring 3, Race 2 โ€“ The 1-2 punch! 

The race begins with a 6-car battle into the first corner making for an exciting start.  Dave sets the pace in class, while Ron, after fending off some light contact from another competitor, sticks to the the Z4Mโ€™s bumper and RoR takes a 1-2 finish in Race 2 for Touring 3.  BOOM! 

GT2 Race 2: 

Simon has a solid start and runs in P3, involved in a 3-car battle for most of the race.  After a restart from a full course caution, several cars experience wheelspin, resulting in a loss of 2 spots.  Despite the setback, he fights his way back up, improving his personal best lap time by nearly three seconds (1:44.5) and finishes in P4
