Wilwood Black AERO6 Front Caliper & Bracket Kit for Corvette C5/C6, Cadillac XLR and Specified Conversion Spindles (1962–2013), OE-Type Iron Rotors

This Wilwood front upgrade supplies black six-piston AERO6 calipers, BP-20 pads and radial brackets for the specified Corvette-type spindle arrangements. Existing compatible iron rotors and hubs are retained rather than supplied. The listed older vehicle applications require their stated conversion spindle; their original brakes are not established as compatible merely by the vehicle model and year. 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

DS927 specifies the suitable OE-type 340mm Z51 or 355mm Z06/Grand Sport iron rotor configuration and the required bracket spacing. Confirm the exact retained rotor before ordering, especially on a C6 with different brake options. Not all Corvette wheels clear; check the 18-inch screening diagram and actual spokes. Select C5- or C6-appropriate hydraulic hoses separately and verify the specific Cadillac or conversion-spindle application conditions.

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