Question autocross setup (Stock Class)???

Hey guys, I won A-Stock last season for the summer series autocross with my stock 95 M3 with R-tires only. What other mods can I do but still remain in stock class to fight off those damn S2000's????

Thanks,

hahah... i hate those s2000s. but i hate your damn e36's even more.

scca rules allow these mods in stock class:
<li>R compound tires
<li>struts
<li>front sway bar
<li>chip (i'm not 100% sure about this, i know bmwcca allows it for stock class)

btw, i ran in AS this summer.
i finished 4th behind an e36 m3, S4, and an s2000.
but i was the only one running on street tires.

what region did you race in? philly scca?

Han.

I do not think chips are allowed in stock class for autocrossing.

I ran the Susquehanna Region SCCA summer series, located in Harrisburg. Next season I am planning on running some Philly events because they attract alot more machines in my class. Only 5-6 months of waiting for the next event...

Thumbs up

You can also get a cat-back exhaust, and use any (or no) air filter that fits in the stock box, and use up to 5mm spacers to widen the track of your car.

Complete rules here:

The biggest help for autocrossing a stock e36 M3 is getting shocks. Look at Koni double-adjustable. Not cheap, but very very nice. I've heard of people using the non-M e36 front sway for stock M3 autocrossing, cheap and slightly stiffer than the M's. Super-light wheels wouldn't hurt either, but hard to find same size as stock.

Oh, one other thing, be sure you're using the smallest diameter tires you can as well, like 235/40s all around or something. Lowers the gear ratio, and gets you off the line quicker.

Your cold air intake is not allowed in stock class.

I'll add a couple of x-tras that people can get away with in stock class.

(1) Short shifter, especially the one from Ron Stygar, looks completely stock and has a bmw part number so it doesn't look aftermarket.

(2) Another easy one is wire a circuit with a relay to turn off the field wire for your alternator at WOT . Unless someone knows what you have done or you do a poor wiring job (hiding it) you can get away with it.

(3) Next: you should have some dedicated tires; paint them with "hotlap/quick time" (found at performance shops) to soften the tires below allowable tread wear rating. Get the brand that is undetectable and run a few ounces in each tire too, to soften from the inside and keep temps from going overboard beyond the tires capabilities. Everyone knows there is cheating in racing. Then the rest is up to you the driver.

Oh, and of course don't forget to keep your gas tank filled just under a 1/4 tank with race gas . You should know by now not to run too close to empty because all that cornering will burn up your fuel pump . Good luck next season.
