I will be hitting my first autocross this Sunday with a few of my friends from our FSAE club. I've never done this before, I've never even been to a car race other than a drag strip, but racing is second nature to me (13 years of motocross/kart racing) so I think I'll do decently well for a first timer.
My question is what should I do for a setup or preparation or anything even close. I'm changing my oil, filter, plugs, wires, cleaning my SRI filter, and finally installing my VF rear mount that has been laying around forever before the race and will also be running 93 octane (plus possibly an octance booster?? is it worth it, or will it actually hurt stuff) Any other tips?
Thanks guys, all your tips will help out tons!!

I'd inflate your tires to around 40 psi hot and bleed pressure as necessary. You can put chalk on your sidewalls to see if it's rolling under, I deally you don't want it to wear past the tread. It's all about getting the most grip out of your tires while keeping them firm.
You can take out your spare tire and jack to save a little more weight. You might want to unload all the loose stuff in there (floormats etc.) at home so you don't have to do it at the track. Good luck.

if you want to get hard core into it, take out the seats, carpet, paneling, etc. every possible ounce you can, however, if you lose that weight in the rear, your car will become a little squimish around the turns and ur car may slide out from under pending on ur suspension setup.

Damnnn Brad you're into this!! It's my DD so I'm not going crazy, I was planning on taking out the spare and jack in the hatch, floor mats, mayyybe the rear seat as it's only a few bolts, and just little things like that. I'm racing a first timer class...apparently against anything from Scion xB's to MR2's but all noobs to autocrossing as well. Tire pressure tips is what I was slooking for. I'm actually about 80% done with 10mm wheel spacers that I'll be running on the front wheels (tires are only 205/40/ZR17) so any bit of width I can get on my stance should help out.

ive run the sam size tire with no spacers...dont really have a issue with handling or grip. thats jsut a nother added thing to maybe cause a problem, (not saying it will) oh also dont be afraid to eat a cone or eff up and spin out. your there to learn car control. so if you go out and look like a wack job (i did my first day, and the first trun every event, i gotta get it out of my system lol) your actually gonne learn 2 things. i'll let you learn them,lol.

I would personaly run 34 front and 32 rear with that size tire.

That seems way low... I would generally run my 215/40/17 Nittos at like 38f and 36r, otherwise I would be all up on the front sidewalls. Just start out high and bleed down until you figure out your optimal grip, all tires are different.

I'll start at 40 up front and probably 37 or so in the back and go from there...also depends on the weather and temp but those will be my starting points

just remember that if you remove the back seats you will go up into another class

They'll stay in there then, lol. That's even for a first timer class?
