Fitment & Compatibility

For Ford Mustang racing brake conversions, compare the replacement with the actual hat and complete brake-kit instructions. A matching flange pattern alone does not establish rotor alignment or caliper clearance. Use the correct dynamic mounting hardware and rotor connection; an ordinary fixed-mount bolt set does not establish the specified floating assembly. This is the rear Mustang race configuration. Wilwood explicitly excludes street use for this hat.
