A question for some of the True Street or drag radial racers out there: Will 28x12.5 ET STreets fit on an 85 Mustang without serious hammering on the wheel wells? The wells have already been rolled. If they will, what's the best rim size; 8, 9 or 10 inches? What about backspacing: 6.5 inches on 10 inch rim, 5.5 inches on 8 & 9 inch rims? We're trying to figure out what the largest tire is that we can run. The car is an 85GT with 363 stroker & 250HP shot of giggle gas with a C4. Previous best with the car is 9.18@149 on 28x10 ET Drags.
Thanks.
