I am just about to go into phase 2 of modding my car, I am looking at going with 18's staggered fitment. Have the rims chosen that I want- Black 2010 GT500 Wheel 05-11 (18x10) at AmericanMuscle.com - Free Shipping! but am looking at going 335/30/18 rears and 275/35/18(18x9)on front. Will the rear tire actually fit without modifications. Also realize if I can go this route, that I will most likely have to drop the car.
