Weld Alumastar backspacing question?
With stock brakes you will need to grind some material off the calipers and use a spacer. Even with a spacer they will still tuck nicely under the front fenders (especially on a T/A).
Probably 3/8" - 1/2" depending on how worn out your pads are and how much you're willing to grind off your calipers. I'd recommend getting a quality spacer (not the auto parts store universal junk) and longer wheel studs (ARP or similar). If you're not set on 15's and are willing to spend some more money the 17" Alumistars clear factory brakes with no spacers or grinding.
