Wilwood Red Front AERO6 Caliper/Pad Upgrade for Corvette C5/C6, Cadillac XLR and Specified Conversion Spindles (1962–2013), Rotor-Retaining Brackets

Red AERO6 calipers and BP-20 pads form this Wilwood front caliper-and-bracket package. It retains the correct existing iron rotors and hubs on the stated Corvette-type spindle installation, replacing the service calipers with six-piston units. Older models in the application list depend on the specified aftermarket spindle conversion and should not be interpreted as original-brake direct-fit applications. 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

Compare the retained 340mm Z51 or 355mm Z06/Grand Sport iron rotor package and caliper bracket setup with DS927. The installation has distinct rotor-size spacing requirements, and nominal wheel diameter cannot confirm spoke clearance. Hydraulic hoses are separate and selected for the actual C5/C6 or conversion chassis. Check every specific Cadillac and older-model spindle condition before the brake package is selected and balanced with the rear system.

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