there is nothing different about your car than a GT when it comes to fitment of wheels other than you dont have any quad shocks....and that only works in your favor because that gives you a little extra room. I ran 17x10.5's with a 315/35/17 tire in the rear of my 03 GT and it was perfect. you shouldnt have any problems. if you order a set of wheels specifically for a mustangs you will be fine, its all in the backspacing. the 10.5 wheels are sized in such a way to fill out your wheelwell to the outside while inside clearance is nearly the same as stock. enjoy! its so worth it.
