Just an FYI and my $0.02 re tire pressures: I run my G Stock 2.5 GL with Hoosier R3S03's. One of the Hoosier reps specifically recommended running at or near 50# for autocrossing to create "artifical heat." Reality is, my times have consistently dropped MUCH lower, with a result that I have 2 seconds this year in Western Ohio Region (Dayton) solos (third got rained out & 4th I was working the GrandAm weekend at MidOhio. I'm sure the pressure thing is also a factor of brand/model tire, but the higher sure has been working for me!
