My track car – 1987 BMW 325is

What: My track car – 1987 BMW 325is

If I knew then what I know now: not a lot… have a larger budget. My track car has evolved as I feel I have needed at a rate that has been on a equal plain as my skill. Could use a little more power now……

Check out: Any of your local track’s and driving schools!

My track weapon of choice is a 1987 BMW 325is. I bought it in 2007 with the idea that it would become my track car. It is what i wanted in a track car, it was in my price range, it was the color I wanted, it was well maintained by the previous owner, and all the work done on the car was at the company/shop I was working for at the time. the only thing it didn’t have was the small plastic late series bumpers. Not to sound snoody but I could look past the bumpers as that was the only bad mark I could come up with when looking at the car. At first i was also going to drive it on the road as well. Well that lasted about two weeks and a car with a bunch of good track race parts that had been wrecked in the guys driveway by a drunk driver became available. This was going to help my rack budget out very much that year. By the time
I had got my parts car home and used what i wanted and parted the rest, I was onto my car pretty cheap. And it had some good stuff at this point. The first parts push ended up with a full Ground Control coilover set, Treehouse Racing front control arm brackets, a set of SSR Comp wheels with Falken rt-215 tires ( in the day one of the top street tires), a new set of stainless brake lines, a low miles E30 M3 4.10 limited slip diff, a set of Powerflex subframe and rear trailing arm bushings, a Momo steering wheel hub adapter, and a new OEM set of euro head lights and grills and a pair of Bride sport seats. I added a set of brake pads, a steering wheel, and a pair of harnesses i had picked up a year or two before on sale. All these ended up costing about $1500. Like I said my track budget looked good that year. others have cost a bit more.

At this point I would say it was still a street car. It still had a back seat and carpet and a radio. I drove it like this for a couple months, but the track bug kept calling. So soon later I found a real race seat. No more reclining. This did now mean I was going to need to look into some sort of roll over protection as I had now defeated that safety measure. I did a lot of shopping and research about fit, style, cost, shipping, availability ect. The one that went in the car was made by a company called VSROne. It had the best clearance and fit in the car. It was not the cheapest option but for sure one I was OK with paying for. Remember I am not a fan of that compromised safety thing. So now the radio has half its speakers, there is no rear carpet or side panels anymore. The seat is in a fixed position. There is scaffolding in the back of the car. but looking forward from the drivers seat it could play the street car part for now……

A couple events into the life there was a thirst for more cornering load. Need to find some tires. Lucky for me there is a local race series that runs a similar car to mine and they tend to go through a lot of tires. So after a little hunting I acquired some real track rubber. in this case early on it was Toyo RA1 tires. These are great tires! They last along time, they can take many heat cycles, they made a lot of sizes, they are one of the cheapest track tires around. If they were still in production I would still be on them. Anyway, now I got some rubber and the car is pretty good. Springs in the car are now a little soft, I can feel the car hitting bump stops and floating a little on the grippy tires. The car already had pretty stiff springs. It was a bit stiff for the street, but not to bad. Front springs were rated ant 375 lbs/ in and the rears 475 lbs/in. At this point I had been working on a few Pro3 cars and had learned a few things. I almost doubled the spring rate of the car. Went to 650 lbs/in front and 800 lbs/ in in the rear. This was the next level of feel I was looking for at the track. Man is it stiff. Think of driving a skate board. So in making the suspension on my car up to track use I ruined the street ride quality. Not the best street car anymore.

Then there was the day I killed the carpet. Was still daily driving the car at this point when almost home from work the heater core blew a end tank and sprayed the entire left side of the carpet with coolant. For me at this point the decision was easy. Yank that smelly coolant soaked carpet out! All the rear was already gone so why not. The heater core fix itself is pretty easy, but the mess was amazing. couple issues I found with no carpet. The car is super loud, the passengers feet can get a bit warm, and I had no place to rest my foot when not on the clutch. So I built a dead pedal for it and that is all I reinstalled. Screw the passengers feet, and I can deal with a little noise, because racecar. Speaking of noise. I have had at least five different exhausts on the car. I bought it with a Dinan muffler, I killed that one looping turn 6 at Pacific Raceways in the rain. Then the custom Magnaflow cat back, this was great until I smashed it beyond repair at a PGP Time Attack on the rumble strips back when you could do that. Then I scored a IE stainless that was on the car for maybe three days, it was way to quite. I then built a Meghan racing muffler catback out of some spare parts. Didn’t look that cool but it was cheap and it worked. This was on the car until it was no longer driven everyday. It now has a pulse tuned equal length header and a flow matched exhaust built by the now closed Volvo custom shop RSI (R-Sport International) when they were developing a Pro3 race exhaust system. The sound on this is amazing but its is on the very loud side.

So now I have been tracking and driving this absurd track car that I have convinced myself is still a street car to the point that it has worn out again. The shocks are all worn and the fronts are dead. DEAD. All the rear suspension bushings, rear wheel bearings, the drive shaft, and a couple other normal maintenance items. So as you should do with any track car i went through and replaced all worn items i found again. I also took this opportunity to think about things I would want to change and the largest one I could come up with was the the shock travel. The car always felt a little held back by the shocks. The valving in them was set for a way softer spring combo, the travel was near the bottom of the shock stroke and they seemed to bottom out a lot because of this. So after much deliberation I got a set of BC Racing coilovers. you can order them valved to specific springs and come with some pretty good hardware. I got a set valved to the springs I had, and because I had springs I had them ship me a softer set (These will be used in another car). I did have to weld the strut tube to my spindle but that is something well in my comfort zone. Once installed and set and tested, I was able to get the result out of the car i was looking for. if felt way better on track, the shock adjustments are now felt, the cat doesn’t bottom on the shocks and they are running in there normal stroke range. I also again made another safety up date at this time. I removed the old race belts and my trusty Sparco race seat and installed a new set of Hans device compliant belts and a Momo head restraint seat. Also upgraded the passenger side belts from 5 pt to 6 pt. Again you can never be to safe.

The look of the car was also something that needed a update. Wheels and tires are getting long in the tooth so lets start with that. We are gonna put a little larger tire on it as well. So off come the old trusty 15×7 wheels and 225-50/15 tires and on go the new Roto 17×8 wheels and the same Toyo tire in a larger 235-40/17. This has created a new problem. The slightly larger size is now hitting the bumper trim and stop the tire. Bring on the fender roller. Little work there and they are in! Thats pretty up to date on the car as of this blog. Still on this seasons update list is a set of Massive Brakes big brake kit and a Diff limited slip unit rebuild. then next season the removal of the old roll bar and sunroof and the installation of a roll cage and clean up the interior wiring. Stay tuned in!

Building a track car – what to buy and what to upgrade when

What: Building a track car – things to consider and make sure you do when building your dream car for the track.

If I knew then what I know now: Power is almost always the last thing to focus on. Most modern cars are plenty powerful enough.

Check out: These are some of the best bang for the buck items for your track day car:

Performance Friction Brake Pads – several models for nearly every application
Eibach Sport and Racing Spring Kits: Solid springs for street and track duties
Momo 1073BLK Racing Seat: Super seat, great price and I’ve been rocking this for years in my street/track E30 (with a roll bar).

So you want to go to the track and don’t have a car yet, but you want something of your own. Cool, what to do now? Here are some key variables to consider:

Overall budget

First thing your going to have to decide is how much money you want to put into this car, that you are realistically only going take on track a few times a year. One major thing is, at the track things, can go sideways in a hurry. Always remember on any given day the track may consume the car, hopefully not you as well but we will go over that here in a bit. The main thing again is to have fun right? If your scared of the car your driving, you may not want to build that car into a track car.

It’s better to drive a slow car, fast than to drive a fast car slow.

Something that was said to me early on in driving was “It was better to learn how to drive a slow car fast rather than be the guy that drives a fast car slow”.

Front-Wheel, Rear-Wheel or All-Wheel Drive?

Also what drive-train lay out do you want? A good rule of thumb is you should track something that has a similar layout to the car you drive all the time. This will best translate the things you learn at the track to the street. OK we have thought about the things above and some personal preferences as well, Time to choose a car.

I like to drive a slow car, fast type of a style. Slow is also a relative term. By modern super car standards a car like a 2002 BMW M3 would be slow with 333bhp and 3400lbs. Think of that for a second, a Mclaren P1 has almost 1000bhp. Three times more! WOW. That being said the BMW M3 is one of the most common cars around due to its chassis, motors, and driver feel. Not just M3’s but most 3 series BMW’s are great track cars. Porsche Cayman, 911’s of all years and 944’s also make good lapping cars. Mazda makes a handful of great cars with good driver dynamics in both front and rear wheel drive. Honda’s, Toyota’s, Nissan’s, Lotus’, Ford Mustang, Gt86 cars, the list goes on and on but most (not all) of the car listed above don’t carry a large price premium to acquire.

You got your car, now what?

Once you found a car its time to take a look at it. A track car should not leak, squeak, rattle, hiss, buzz, clunk or shake. Any of these items will need to be addressed before even the first track event. You must have a reliable car to take to the track. Breaking down or oiling down the track doesn’t only ruin your day but all others as well do to lost time from cleanup and decreased track condition.

Car up on stands getting checked out before the next event.

Lets get it ready to go fast. What are the two most important systems in a car? Steering and braking. At a minimum the entire suspension and brake system should be inspected with a fine tooth comb. Replace any and all worn items. At this time depending on what is worn out an upgrade may get to pop in.

Lapping prep basics has taught me that having a set of track brake pads is the most beneficial item you can do to your car to make it last the entire day. Nothing worse than calling it a day because you used all your brake pad in two session. I would also try to do braided brake lines at this time as well. They just help with the pedal feel when you really get on it hard. I have always had great results with Performance Friction Brakes, Carbotech Brakes, Stoptech brakes, and Wilwood brakes for pads, brake lines rotors, and calipers. I could be happy with this prep level on a car. Driving a car on soft suspension and street tires with killer brakes can be a hoot!

Good pedal placement and a clean foot well can make heal toe shifting easier.

Brakes – check! Shocks and Springs are next!

So you have done a couple days now and the brakes are good but you are gaining a thirst for G force. Whats next? Lets do some shocks and springs. I would suggest going with a coil over setup with a linear rate spring (most good kits are). Having a shock and spring combo that works together as one makes a car become so much more predictable. The build up to the adhesion limit is far less sudden in this case. Sway bars are a common upgrade as well. That being said a good coilover setup (read chassis tuning) may not require them. A lot of times I have put a stiffer sway bar on a car only to place it at full soft or in some cases remove it all together. I would stick with one step at a time on this one. Bushings are a great upgrade as well for chassis stability. Street cars are built to be quite and comfy. These rubber stockers allow some chassis parts to move a lot as to not upset the ride comfort. At the track this movement will cause the car to never feel like it really takes a set, always kinda moving around. In the past we have used Ground Control products, BC Racing products, Fortune Auto products, JRZ shocks, Motion Control Suspension and would not hesitate to use any of them for future projects.

The Meaty Tire Thread!

A set of good track rubber is always fun. A good set of R compound tires can up your grip game by a massive amount. The soft grippy compounds and large tread block size allows the tire to stick to the road once it gets to operating temperature. The tread blocks being as large as possible keeps the tire tread pattern from deforming or getting torn off as they pass there heat tolerance. This can have a side effect that can catch you off guard. The enhanced grip level means your speed is higher and your lateral load is higher and the then sudden loss of traction at the tire limit is much more dramatic than it would be on street tires. Most good tires do give you some warning before they will slide.

There is nothing that beats that grip though. Toyo Tires, Nitto Tires and Hankook Tires make good lasting, high grip, user friendly track tires. There are many others but keeping cost in mind these are what I shop for most of the time. Check out Tire Rack for usually solid deals and good availability.

More Speed Requires More Safety – Don’t Skimp Out on Your Life

Well now the car has better brakes, an upgraded suspension, and we have some nice grippy tires. That means we are moving pretty fast now. One of the thing I have learned in my years going to the track. Safety is NOT over rated. The better the safety gear the better the chance you can walk away from a big one. Good basic safety harnesses do a great job of keeping you planted in the seat at the track. Even a set of four point belts with a stock seat can get you headed in the right direction.

Being able to stay planted in your seat with out having to hold yourself into the car allows you to have smoother, softer inputs that upset the car less in a reaction maneuver. Upgrading the seat to one with deeper sides and some better shoulder support just bring your stability in the car to the next level. A note to remember when shopping for seats. It is not recommended to run a fixed back racing shell without some type of rollover protection. In the case of a rollover a reclining seat is designed to fold/ break in a way to prevent the occupant from being crushed if the roof caves in.

Sorry if this is sounding a little dark but its the real deal. If you were in a rollover with a racing seat the seat would not fold and the roof would make contact and there is a high chance of getting crushed. A roll bar or roll cage is never a bad idea when going fast. I have run a rear roll bar and a race seat for years in my track car. Just having the piece of mind of knowing I have done the best I could with the budget I had, I felt as safe as I could be for the speeds I am driving. I am planning on installing a full cage in my car as the plan for speed increases.

I also run a set of six point harnesses, a Momo head restraint seat, and a Hans device attached to my Arai gp6 helmet. More on helmets later.

Fire is also a possibility. With increased speed comes increased stress and increased heat. There are many combustible fluids in a car: fuel, oil, brake fluid, gear oil, and that is just some fluids. A track car should at minimum have a small fire extinguisher. A complete fire suppression system plumbed into the car is best. They are not that much money in the grand total. Bimmerworld sells a kit for a few hundred dollars. When you have spent now thousands of dollars, it seems like a waste to have is burn to the ground because you didn’t want to spend a little more. Sparco, Momo, OMP, Schroth, Arai, Hans, Alpinestar, Adidas are all brands I would recommend.

How about that. Now we have a sweet track car. The car of our liking, the one that fits you like a glove, the one you have always wanted. It’s all leak free and reliable. It stops on a dime with the sweet brakes, it drive like its on rails with the tuned suspension, it has the grip from the sticky tires, and you have piece of mine being planted in your car with all of your protective gear keeping you safe. Now you can worry about you at the track rather than if the car can handle what your putting it through.

If you noticed I never got into adding power. The things above will make your car much faster than you think. Being able to hold a higher corner speed and have a shorter stopping distance will get you way better lap time results than just tossing horsepower at it. It all needs to work as a balanced package. Once you want to add power after your skills have bounded, a key item to remember is not to add to much. You don’t want to have more power than the car, tires, brakes, ect can handle. Back to the scary car thought. Its always easy to add more power to a car. So I say just roll it in rather than shoot for the moon.

My Track-car Saga (Abridged)

What: The decade long story of me trying to build a track car

If I knew then, what I know now: I would do the same damn thing

Product to check out: Strait jacket. No seriously, like for the crazies. But try to get a fire-resistant one so you can wear it on the track!

My first cool car – 1993 BMW 325i

One of the things we would like to share are some of the projects that we are working on during our own free time. I will share the tale of my track car that I am building. It starts many years ago, and actually involves several cars at this point. The story goes! In 2004, I bought a 1993 325i from a nice couple and started driving it. I was always a car guy, and was one year graduated from high school and really wanted a “cool” car. This is what I ended up with. I loved that car and drove it everywhere I could!

As the years go past, I became more of a race participant, than a fan. I started working at the track on the weekends helping people with their race cars and stuff. At the same time, I also started getting into driving as a sport more. My BMW was the perfect delivery device for an entrance into motor sports. It was a good solid car, had good power, great brakes and handling. I started to modify it for auto-cross, then eventually took the next step and started to prep it for track days. I did a few track school days and got really hooked. From then on, I was building a race car!

Transitioning from a ‘street’ car to a ‘race’ car

I stripped most of the interior out of the car to save the weight, also removing the sound deadening at the same time (which was a BIG job!). I got a fixed back racing seat, and a roll bar, some harnesses. I made it loud. Put a performance clutch and flywheel in it. Installed a shorter differential, got bigger brakes for it. And was still driving the car everyday. It was fun, but loud and uncomfortable. I loved it. I drove over 100k miles in that car while I had it, but ultimately had to sell the car just short of it being a full race car due to a crash I had while driving a fellow racers car (that will be a story for a different day!).

I made it loud. Put a performance clutch and flywheel in it. Installed a shorter differential, got bigger brakes for it. And was still driving the car everyday. It was fun, but loud and uncomfortable. I loved it.

We had gotten into Chump Car racing and had helped some people on a few events and as a result, had earned a chance to drive the car for a 36 hour race in Spokane in 2013. I had never driven at Spokane before, and was a little nervous, but was feeling OK because we were racing the same car that I drive all of the time, an E36. I was racing hard with the front runners during the race when I lost track of my internal map, and made a poor move to pass that landed me on the dirt. I lost it, and the car was wrecked. Then I had to pay for it.

Going racing always carries risk

I ended up selling my beloved 325 to a very close friend of mine. He was a fellow racer, and had been looking for a chassis to do his own build on. My car was a prime choice for him to use, and we struck a deal. I was able to recover and pay for the car I crashed by selling my race car. That was a hard lesson, but a very valuable one! I learned that your track car, can be gone in 2 seconds and there may be very little you can do about it! It took a little bit of time for me to start thinking about my 325 after selling it. But as time past, I missed it more and more.

Three years after the crash, I was able to get back into a race car again, and felt very good when doing it. I then went on the hunt for a new track car. I found a 1994 325 that had some decent prep done by a nice couple that was going to turn it into a rally car. I found it on Craigslist after they just ended up going out and finding themselves a finished Volvo rallycar to use. I bought the car, and it felt like home! I Started getting it ready to track with and found a couple of good deals online for some good used race bits. The game was on.

Getting goldie all hooked up!

There were a few things it had been prepped better and that I had not done yet on my previous 325, but was not nearly as far a long in other areas. I started to chip away at a to-do list and now it is starting to shape up nicely! This is where the story starts to get interesting. In an attempted to get the new 325 spec’d out like the old one. I struck up conversation with my friend who had bought mine before. He had not really done much with the chassis, and was maybe thinking about getting rid of the car to do something else. We talked about it a few times over the next couple of months, and eventually came to a deal for me to buy the car back from him! The idea is to get a lot of the cool or good stuff I had before swapped over to this new car since it was much more complete at this time.

Two become one

As of today, I have the two cars in the shop currently becoming one! It has been a very long process, but I am very excited to have gone full circle and have a car to use for track days and racing that I will be proud of. I like the idea of building one over buying a car. You have the chance to spend way more money doing so, but by building the car yourself, it is bespoke, and custom fit for YOU. That is what I find so great about it. The car is my version of what I think is a good way to hit the track! There is no right or wrong way, but the more miles you log, the more you will know what you want to do and do not want when you are out there! I will share more as further stages of build happen! I would say that this car is my “baby” but it will never be treated like a baby. It will be used, hard, but well cared for. This is my racing appliance! Thanks for letting me share some about my track car build, and always remember to have fun!
