good to know. i plan on lowering it about 1.5 inches like most people and i just picked up a set of 18x8 AE 077 wheels in a mustang pattern, so the cobras are out (for now). from what i've researched they are the same offset as the GM pattern but should still fit with the Ford mustang pattern. i'm going to put one on tmw and see how it works out. will i need the engine spacers if i lower it 1.5 inches? did you guys have any problems? ive read some that have and some that havent. any recomedations on tire sizes from any prior experiences?
