Wilwood Front Black Superlite 6R GT Brake Kit, Ford Fairlane/Falcon/Mustang/Ranchero/Torino and Mercury Comet/Cougar/Cyclone/Montego (1968–1970 Disc Spindles), 12.88-Inch Rotors

Six-piston Narrow Superlite calipers and 12.88-inch GT slotted rotors form this Wilwood front hub conversion. Black radial calipers, replacement hubs and separate hats are configured for the early Ford/Mercury disc-spindle arrangement. The 1970 Mustang GT350/GT500 entry must be distinguished from the later disc-spindle family. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Follow the exact Fairlane, Falcon, Mustang, Ranchero, Torino or Mercury application row rather than applying the combined year span to every model. DS590 covers the 1968–1969 Mustang disc spindle; the application table identifies additional matching configurations. Check the +0.25-inch wheel offset change and the wheel template. Hoses are separate, and master-cylinder pushrod work depends on the installed cylinder and pedal arrangement.

Match the individual model, year, submodel and brake configuration in the fitment table below.
