will older model stang wheels ( 15 inch) work without rubbing the disc brake caliper? bolt pattern?
CHECK WITH YEARONE AND ASK THEM.
It's difficult to say for sure for each and every possible wheel, but while Ford factory 15 wheels can be fitted to 99-04 GT's and V6's because of the size of their brakes, Ford never fitted any of the cars with the 13 PBR brakes (Cobras, Bullitts, and Machs) with anything smaller than 17's because they did not fit over the caliper. That being said, I know that some people wanting 15 drag wheels on the front of said cars have made some modifications to make it happen, for instance, spacing the wheel out away from the caliper and then grinding the caliper down some so that the wheel will fit, but I've never heard of a simple bolt-on solution for 15 wheels fitting over the 13 PBR brakes on a Mach 1. Good luck!
