but the offset is where we run into problems for aftermarket wheels. All the mustang wheels run an offset for RWD. FWD requires different offsets then RWD. Points to ponder. When shopping for wheels it is best to go to a wheel store and have them hang a wheel on car and check clearance issues. Any reputable shop should be able to perform this task. Other wise unless you know you are getting the proper offset you are shooting in the dark when ordering wheels online as to fitment ie no rubbing when turning the wheel from lock to lock.
