Autocross Setup

[base9se]

I just recently did my first autocross and enjoyed it. I would like to know how much pressure I should put in my tires. I am running Kumho 712 215/55-16 (Front) and 225/50-16 (Rear). I ran them at 39-40 PSI all around last time. After the event, I talk to some 240 owners and most of them said to run 36-38 for the Front and 38-40 for the Rear. Does that sound right? I also set my KYB AGX 2 (Front) and 4 (Rear). Anyone know what the best setting for them would be?

I'm no expert, but I run 36PSI front and 34PSI rear with 205/55/R16 Yokohama ES100s. Take some chalk or shoe polish with you next time and mark across the edge of all of the tires to see how much roll over you have and adjust accordingly.
