first autocross
Just thought I would share with everyone my first autox exprience. First what I have done to my car, subframe conn., tubular lca, adj. phb, wonder bar, edlebrock stb, lowering springs, kyb gr-2, new poly bushings everywhere, bridgestone g007, 3:42 peg leg, stock motor, stock tranny, ls1 rear brakes. All that put me in STX.
I am the 87 ta, my buddy was in the 89 rs in SM. Wife had dibs on the video camera. I ended up fairly consistant with one freak run that I ruined with some cone kills.
Now the list of stuff to fix before the next time I go, tires as these lost all grip after they heated up, and seats with more support!

Re: first autocross
So....... Are you hooked yet? It is addicting
After my first event I started to get serious. AWD Dodge Stealth twin turbo. By the second event it had fuel system mods and larger turbos, By the third event it had a set of adjustable coilovers and some soft Hoosiers on another set of rims. Now I am having a blast with the Camaro. Unfortunatly the Stealth was faster then the Camaro.

Re: first autocross
I was hooked after the first run! Infact I am still giddy about it Any advice on tire pressures? I had a couple people tell me inflate to max before and work down. What is better for autox more air or less?
Also the longer corners kinda got me, if I pushed it I felt like I was going to flip over, my imagination, prolly because of sliding around in the seat so much.

not my cars, but you catch a glimpse of my silver ta in the pits with the hood up. The track setup was great for what they had to work with.

Re: first autocross
Big heavy car on street tires? You will probably end up at 40-42 PSI to keep the sidewall from rolling. Out a couple dabs of shoe polish where the tire curves into the sidewall, you will be amazed at how far they roll over.

Re: first autocross
Go to harbor freight and get a temp gun after a run shoot the tire tread in 3 places (inside, middle, and outside) these readings need to be very close to one another. check all 4 tires, once you get the temp readings as close to the same you are at proper inflation and maximum grip.

Re: first autocross
Yup, That's right around where I was when I was on street tires.
I had more air in the front than the rear to hook up better.
Even with some stiff sidewall Hoosiers, I still used to get a decent amount of sidewall flex as shown here. (skip to 56 sec. mark)
