Product details

This front Dynalite conversion pairs red four-piston calipers with 12.19-inch SRP drilled and slotted rotors for the specified early GM disc spindles. New hubs, bearings and mounting hardware provide the rotating assembly, while spindle machining remains an essential part of installation. Founded in 1977 by Bill Wood and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to work together within a properly matched brake system.

Fitment & Compatibility

For the listed 1970–1978 GM passenger-car applications with the specified factory disc-brake spindle and original 11-inch rotor arrangement. Camaro and Firebird are included alongside the qualified Buick, Cadillac, Chevrolet, GMC, Oldsmobile and Pontiac entries below. The spindle configuration, rather than the badge alone, determines compatibility.

Installation requires substantial steering-arm/spindle work, including drilling and tapping mounting holes and removing interfering ears. Wilwood recommends a qualified machine shop. Hydraulic hose kit 220-10509 is separate; confirm its routing for the exact vehicle.

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.
