just picked up a set or 18inch chrome saleen wheels which do have the saleen name stamped on them, anyway i put them on and noticed one sticks out on the front more than the other well i mesured the wheel thickness, and 3 of them were 2 3/4 and the one sticking out is 3 1/4 im guessing this means there are different offsets?????????? where can i get on to match it????????
