Wilwood Chevrolet Bel Air/Biscayne/Impala/Caprice Front Disc Conversion, Red Calipers and 12.88-Inch GT Rotors (1965–1968)

Fit red Superlite front calipers to listed Bel Air, Biscayne, Impala and Caprice drum spindles. Hubs and GT rotors need the correct wheel fit. The conversion combines the caliper, pad and rotor configuration specified for this axle and mounting arrangement. Camarillo, California, is home to Wilwood Engineering, the disc-brake manufacturer Bill Wood founded in 1977. Wilwood designs and manufactures systems and components including master cylinders, calipers, rotors, valves, fittings and brake lines. Those parts serve motorsport, street-performance and specialized uses and must be selected as part of the complete brake system.

Fitment & Compatibility

Fits the listed 1965–1968 Chevrolet Bel Air, Biscayne, Impala and Caprice applications using the specified factory drum-brake spindle. Caprice coverage begins with the 1966 rows. Confirm the actual spindle before ordering; the later single-piston factory disc spindle is a different selection. The supplied hubs have 5 × 4.50 and 5 × 4.75-inch wheel patterns with 1/2-20 studs. Select the correct pattern, verify tire position and compare the clearance drawing with the actual wheel. Compatible brake hoses are not included. Use the fitment table below to confirm the individual model, year, submodel and brake-option restrictions.
