Wilwood Red SX6R Front Brakes with Drilled Dynamic 15-Inch Rotors for Listed Ford Falcon/F-100/Mustang and Mercury Comet Hub-Spindle Applications, Including Mustang 2015–2023

Red six-piston SX6R calipers and drilled-and-slotted rotor rings form this 15-inch front conversion. Dynamic lug-drive hats connect the friction rings to the specified retained hub, while the chosen suspension application determines bracket and hydraulic fit. Founded in 1977 by Bill Wood, Wilwood Engineering is now based in Camarillo, California, where its work centers on disc brake systems and components. Calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized installations; selecting these parts requires considering the complete braking system.

Fitment & Compatibility

Check the separate modern Mustang and Ridetech conversion entries without extending one configuration to the other. Listed Falcon, Comet and F-100 installations require the approved hub spindle; earlier Mustang rows require the specified Ridetech arrangement. Verify the 19-inch wheel drawing and the supplied hose's chassis connection.

Check the application-specific restrictions for Falcon, Comet, Mustang, F-100. A shared model name does not replace the exact year and brake/suspension configuration. 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.

PMB Performance has over 20 years of experience with parts and fitment details. Contact us with the original vehicle specification and any changes to its braking or suspension system.
