8 3/4 rear disc brakes question

I guess it depends on what kit and how the wheel is constructed. I bought my rear Caliper adapters from member @dodgedifferent2 and then sourced the rest of the parts locally. It’s based on the 94-04 Mustang. I figured I would be using 15 in J Body 10 spoke aluminum wheels and was really surprised that 14 in Magnum 500’s clear the calipers no problem. 14 inch Rallyes would not clear the calipers.
