Jason,
no offense, i like these wheels, but I think the offset on the front is way too aggressive. Are the offsets +15 for rear and +17 for front?
I think you are going to have a serious rubbing issue when the car is lowered unless you go with some real aggressive camber and stick with the 255's
Check out Dannys thread, his wheels are 9.5 in front with a +22 and he had some minor rubbing issues, although he is running a 275.
