I'm still fairly fresh with HPDE (6 days on track). I've pushed my continental extreme contacts to their limit, and I'm ready for some more grip. Especially with some of the new stiffening suspension mods I've done recently. I'm looking for a 200tw tire to fit on some 18x10s. I'm running 19" wheels right now with 275/35/19. I'd like to stay at that width but maybe a 40 series profile. I've heard good things about the hankook rs4s and the dunlop direzza zIII, but I want to see what kind of tires you guys have had luck with.
