Product details

This later-GM front hub conversion combines black Dynalite calipers with plain 12.19-inch rotors. It is built for the specified 11-inch-rotor disc spindles and requires the machining described in DS504 before the new brackets can be installed. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are all part of Wilwood Engineering’s range of disc brake systems and components. The Camarillo, California company was founded in 1977 by Bill Wood and designs and manufactures these products for motorsport, street-performance and specialized applications. Compatibility with the complete brake system determines the appropriate component choice.

Fitment & Compatibility

This hub kit is for the specified GM factory disc spindles with original 11-inch rotors. The application list includes 1979–1981 Camaro/Firebird, selected 1979 GM compact models, the listed full-size cars and wagons through 1985–1986, and Caprice through 1990. Match each model-year entry and spindle requirement rather than assuming every GM car in this range is covered.

DS504 requires substantial spindle/steering-arm machining, including drilled and tapped bracket holes and removal of interfering ears. Have a qualified machine shop perform the work. Front hoses, including the listed 220-10509 reference, are separate and require vehicle-specific routing checks.

The wheel contact surface must seat fully on the hub. If it overhangs the hub face, Wilwood requires the separate 6.60-inch-diameter x 0.20-inch steel spacer 300-11961. For stamped-steel wheels that do not overhang, Wilwood recommends the 6.15-inch x 0.09-inch hub shield 300-10716. Inspect contact surfaces and follow the wheel maker’s tightening requirements.

Use the fitment table below to confirm the exact model, year, trim and all numbered application notes.
