Time to help out the tire guy and his GT500

[blacksheep-1]

I scored some 18x10 wheels and am looking for some tires, currently I have Goodyear supercars 255/45x18 and 285/40x18...I'm looking for something a bit wider, I can change the tire size in my tune, if needed, then slightly larger (more sidewall) in the rear would be good. Car is currently not lowered, but I can see that coming. Tymeslayer has a nice setup, but his are 19s.
Probably a 200 tread wear rating since to remain in my stock autocross class they require that.
thanks in advance.

Hankook R-S4 and Falken 615k+ both come in 295/40/18. Both should be very sticky although I have no experience with either (used to run original 615s on my Evo and they were fantastic).
