A set that has been painted to match the car, are on the picture above. Front tires are Kuhmo 205/65X16 and the backs are 235/60X16 - 180 MPH rated. 25.6 diameeter in front, 27 in back. The front is a Turner brake conversion and the back is Ford Explorer [10 1/2] on a Currie 9" Rear end. The front end also has one coil cut out of the front spring. NO CLEARANCE PROBLEMS AT ALL - front or rear. A friend has the 16" rims on his GT350H mustang, but will soon be going back to the Halibrands, and the 16" rims will be available if you are interested. PA Still have your wheels?
