No, after machining of the Mustang rotor the wheel is in the same position as it was from the factory. The only comment I`ve heard is that sometimes an extra washer may have to be added to the end of the spindle before the locking nut is installed. It seems that some of the spindles are not threaded deep enough so that the lock nut will tighten down without bottoming out first. This may indicate that the wheel is further in the width of a washer.
