94 Mustang Wheel Question

[Lee Jordan (3223) A/S]

I run mine with 15X10's on the back with the 30X9" Goodyears. 5.5" backspace but I had to clearance the front edge of the wheel well and roll the lip opening. I was rubbing when at speed with the tire roll-out. The sides would rub when the car squats good without rolling the wheel well. I think the disk brake 8.8 housing is 3/4" wider than the older drum brake cars.
