Well I will be installing a new clutch and Lightened flywheel this week, which I believe puts me out of STR. So I am looking at R compounds and I'm trying to decide if I should do a 225 square setup, or 225's front and 275's rear. So is 275 too big for the power of the car? (Right now I just have exhaust and intake, and soon Lsd and lightweight flywheel) Also, its alot of stagger, so theoretically it should understeer, so ill probably run little camber in the rear (-1.5?) and more in the front (-3?). I have never run R compound slicks before so I really have no clue, any suggestions?
