I run 235/40/18 bridgestone potenzas inflated to 40psi on +38 (shit)offset RAYS Volk lightweight wheels, stock diff I think, and a measly 200rwkw. The car came with Cusco adjustable suspension which is too hard for my liking, and is lowered to ok height.
I spin first easy and second spins a fair bit too when giving it some stick driving straight, it usually side steps, I never LAUNCH. I would really like to avoid this spinning and sidestepping, I think I'm running too much tyre pressure, too skinny tyres with bad offset and a hard suspension, maybe get some pineapples, would like to soften er up...hmmm
