Wilwood Front 12.19-Inch Plain Rotor Kit, Black Dynalite Calipers, Chevrolet Bel Air/Biscayne/Caprice/Impala/Brookwood/Corvette/Kingswood/Townsman/Estate (1968–1982)

This Wilwood front brake kit uses 12.19-inch vented rotors and black Dynalite calipers for the specified Chevrolet spindle family. Plain friction faces and BP-10 pads are paired with new hubs, bearings and application brackets. The larger ring package has its own wheel-clearance profile and per-side mounting offset. 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. Its product range serves motorsport, street-performance, and specialized applications, with individual components selected to match the requirements of the complete brake system.

• Included: paired calipers, pads, rotors, brackets and assembly hardware, replacement hubs and bearings.
• Hydraulic flex lines are separate. Master cylinder, booster and spindles are not included; retain or select suitable matching components.
• Conditional minimum wheel diameter: 15 inches. Verify the complete clearance drawing for barrel and spoke offset before purchase.
• Wheel seating: the specified support spacer is required when the wheel contact face overhangs the hub. The support spacer is sold separately for this kit. For stamped steel wheels without overhang, use the specified hub shield, obtained separately.

Fitment & Compatibility

The conversion must be checked against the fitted Chevrolet spindle, not simply the chassis model name. Full-size cars have separate drum- and disc-brake year entries; the C3 Corvette uses its own stated coverage. Consult DS833 for bearing assembly and bracket placement. Before removing the old rotors, establish whether the chosen wheel's mounting face projects beyond the hub: the specified support spacer is a separate purchase where that condition exists. A stamped steel wheel without overhang instead needs the specified hub shield. Account for the outward wheel-position change, select hoses for the actual chassis and verify the conditional 15-inch clearance envelope. The larger ring does not make a smaller-brake wheel compatible.

Check the individual year, model, submodel and equipment conditions in the fitment table below before ordering.
