Let talk about the width of your rear end first.

That tells WHAT it is, but not how WIDE.

Any rim will fit, if the backspacing is picked out correctly, which can be determined more by the width of the axle.

Gotta have the width to start with...

The thing that confuse me is, when I give a full turn to the front wheel, will it rub the fender??

Re: Which Enkei or BBS rim will fit under 91 trans am with 9" ford rear end

Your not going to put 14" brakes on the back end of that car???

What is needed is a measurement from the rear brake hub to rear brake hub, or you could tell us that it was ordered for factory width. Then you will get some better replies.
