2005 BMW M3

Posted: October 6, 2016 in My Cars

Less than 24 hours after registering at the DMV and she’s got slicks and race numbers on her.

I blacked out the grille and gills.  The boys at PAD gave it thorough cleaning.

Class legal modifications include headers (with a cat 6″ downstream), shark injectors, pulleys and an intake tube.

Oh, and some Moton Club $ports.

One last photo before surgery.

The headers went in with some work.  You have to remove about 1/4 of the engine bay to access all 18 bolts holding on the factory header.  Then, you have to remove all of the factory studs and replace them with the aftermarket studs.  Finally, you have to jack the car up and insert both headers simultaneously from a vertical angle.  I’m telling you this because it took me about 3 weeks to figure all of this out.  BUT – the eBay fitment was perfect and HOLY COW does this car rip with the headers and tune.

Installing the shocks was not difficult.  Routing the remote reservoirs was a little more work.  For the fronts, I removed the fender liners and snaked the reservoirs up into the engine bay, mounting them to the radiator shroud with zip ties, because I’m classy like that.

Mounting the rear reservoirs required full removal of the bumper.  There are plastic vents that I removed and made small cuts to allow the hoses to fit through.  I mounted the reservoirs to the trunk brackets – with zip ties of course.

The Ground Control bars were a bit of work as well, but they are so fancy and so adjustable.

With the factory 19×8/19×9.5 wheels and 26″ diameter tires package, fitment was troublesome.  With my race setup 18×10 front and rear with 25″ diameter tires, fitment was a little better, especially once I learned how to do an alignment in my garage and dialed in -3.5 degrees of camber in the front.

After a professional corner balance, she’s ready for battle.  I dialed in -3.7 degrees of front and -2 degrees of rear camber – a little more front and a little less than I wanted.  I’m also running a tick of front toe out and more than a tick of rear toe in.

The car weighed in at 3,476 lbs.  Time for a diet.

Step 1: Replace heavy ass leather/power seats with manual/alcantara.

Step 2: Replace the 50 lbs OEM battery with a 24 lbs Miata battery.

5/21/2017 – First race, first place.

The car was loose, very loose.  So loose that I didn’t push the tires to their optimal happy slip angles – but it was still fast as all hell.  First in class and 3rd/53 for raw times.

I cannot run more tire in the rear (although I could run more wheel).  I started by dropping some compression in the front which seemed to help until it rained.  Next event I will drop some rebound in the rear and see what happens.  I can also add some more front bar, take out some front camber, or play with the pressures (which I didn’t even bother checking).  In addition, I could not be a pussy.

So, for the next event, I spent some time at test and tune the day before.  I dropped tire pressures to 29 r/33 f and I am running 2 compression front and rear with 2 rebound front and 4 rebound rear (factory suggestion is 3 compression front and rear and 4 rebound front and rear).  The results?

First in class and 2nd/98 in raw times (I got beat by the damn Formula car).

Throughout the season I continued to drop both compression and rebound in the front and the rear.  The car is currently sitting one off full soft in compression and rebound at front and rear.

After chewing through a set of RE71rs, I flipped them on their rims, but the wear continued.  I bought new tires and went to 0 toe front and rear.  I actually like how the car drives better without any toe.

In addition, a full season of beating has taken its toll on the front bumper.

Plans for the winter included a custom single exhaust, pulleys, some maintenance, a “custom” intake like on my 318ti – and perhaps some bodywork.  Or not, since it’ll just get messed up again next year.

My welder wasn’t available this winter, so I clamped together an exhaust that included a catalytic converter for class legality.  Eventually I’ll use real bends instead of flex pipe and actually weld things, but for winter storage this will do.

My wife hates this exhaust.

I also did the pulleys.  Not worth posting pictures.
Finally, I bought some Ikea seats on eBay that required me to assemble them myself, without any provided hardware.  They were cheap and included brackets that actually fit (and worked with the stock belts and wiring), so that made me happy.  They’re also light as all hell.

It’s gonna be a race car.

Step 1: Add lightness

Step 2: Add power with a “custom” intake.

Step 3: Mount truck tires

Step 4: Race

We added a little more lightness during our first event by ripping off two fog lights and the front grille.  We also discovered that 1st gear is more than enough with the tires.  Finally, our suspension travel not only makes for a pillowy smooth highway ride but also works rather well in an off road setting.

Rarr.  We also broke the exhaust.  One of the bolts snapped right in half.  Time for an upgrade?
