The Campi's fit great on the Mustang. Better than they did on the Pantera in fact. I have 265/50x15 BFG Euro TAs on 7's in front and 295/50x15 BFG Euro TAs on 8's in back, and they _completely_ fill the wheel wells. I had to massage the rear inner fender panels (i.e., pound them with a 5 lb sledge hammer) to provide enough clearance for those big tires, and I could still use about an 1/8" to 1/4" spacer on the rear to move the tire out closer to the outside (it still hits the inner fender on some hard turns). The rear outer fender edges are also rolled up (just as previously discussed for Panteras) and the front fenders are OEM Shelby fiberglass pieces with "rolled" lips. The fit problem with the Mustang is ball joint clearance on the inside of the front wheel, it can only stand 3.5 to 4.0 of backspacing (0 offset on a 7" or 8" wheel) with normal 15" diameter wheels. Larger diameter wheels could possibly eliminate this problem. Also the Mustang can take about 1" more backspacing in back (if the inner fenders are adjusted) without hitting the leaf springs. These tires are very big for the wheel widths, consequently they roll over the rim edge quite a bit (ideal rim width would 1-2" more). This is not ideal in a real performance handling car, but my Mustang is more of a cruiser; the convertible chassis, an automatic trans, and a 428 engine to not produce ideal handling characterisitcs. This tire roll over makes the wheel width more of a problem, as wider wheel might fit if a smaller tire with less roll over were used (as long as it does not hit the inner ball joint).

I thought when I was researching new wheels for the Mach I, I found I needed a 0 offset. If this was so, how well did the Campy's fit on your Mustang?
