Fitment & Compatibility

For Ford Mustang 1994–2004 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. Select the rotor and attachment hardware separately for the documented assembly. Follow the installation drawing for engagement and clearance at every mounting point.
