Sidewall is a must. Im running 255/35/18 rear 225/40/18 front. I have been eyeballing some 245/50/18 all around. The rims are style 71 chromadora rims. Two piece setup, 18/8 front 18/8.5 rear. I have hub rings coming. Far as my suspension, im going to upgrade from stock only cause I have FE1 suspension. Just some nice bilsteins, slotted rortors maybe, I want the brakes a little more "grabby".
