Wilwood Dynamic 14-Inch GT Front Brake Conversion with Red SX6R Calipers for Listed Mustang (2015–2023) and Ridetech Ford Falcon/Mustang/F-100 or Mercury Comet Applications

The red GT-rotor option supplies SX6R service calipers and 14-inch dynamic rotor assemblies for the documented front hub interface. Aluminum lug-drive hats, bracket hardware, pads and flexible lines form the matched conversion components. Wilwood Engineering has designed and manufactured disc brake systems and components since its founding by Bill Wood in 1977. The company is based in Camarillo, California, and serves motorsport, street-performance and specialized applications. Its calipers, rotors, hydraulic master cylinders, valves, fittings and brake lines need to be matched to the complete system in which they operate.

Fitment & Compatibility

Compare the retained factory Mustang or approved Ridetech hub with the exact application below. Earlier Falcon, Comet, F-100 and Mustang rows require the specified aftermarket suspension rather than a standard original spindle. Confirm the 18-inch wheel envelope and chassis-end hose fit.

The application list names Falcon, Comet, Mustang, F-100. Verify the particular year and suspension/brake option for each model. Use the fitment table below to confirm year, model, trim and brake or suspension options.

Choose any alternative flexline for the actual route and chassis fittings, with enough travel and the correct flare connections.

For a fitment check, give PMB Performance the vehicle details and the actual brake and suspension hardware. Our team has over 20 years of experience working through parts compatibility.

Check the Installation instructions for the full assembly and wheel-clearance requirements.
