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.
Bought several pirate jacke front disc conversions no issues on 14" ralleye. Was looking at them havnt had chance to call just wondering what people
did conversion on rear and info concerning 15" wheels
