Wilwood Black Superlite 6R Front Disc Kit, Chevrolet Impala/Corvette/Sedan Delivery/El Camino/Bel Air/Biscayne/Nomad/Brookwood/Kingswood/Parkwood (1959–1964), 14-Inch SRP Rings

Wilwood supplies drilled/slotted 14-inch rotor rings with black Superlite 6R calipers in this front hub conversion. The SRP package includes BP-10 pads and 72-curved-vane Spec-37 rings on separate hats. It is configured for the listed early Chevrolet front spindles, including the specific early Corvette entries rather than every later Corvette brake layout. 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

Begin by identifying the original Chevrolet spindle and comparing the bearing and bracket dimensions with DS904. The selected combination uses BP-10 pads and drilled/slotted 14-inch rings; preserve that component match when planning replacement consumables. Fit the wheel studs to the appropriate hub pattern and confirm complete wheel-face seating. Each wheel moves outward 0.21 inches with this hub arrangement, requiring a tire/body check before the 18-inch caliper screening diagram is assessed. Hydraulic hoses are separate and must remain clear at full steering lock and suspension travel. Confirm master-cylinder displacement, pedal travel and brake balance with the installed rear package before following the assembly and minimum test instructions.

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