Prepare the listed GM disc spindle for red six-piston front calipers and SRP rotors. Confirm the required spindle machining and wheel backspacing. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components. Bill Wood founded the company in 1977. Its calipers, brake rotors, valves, master cylinders, brake lines and fittings serve street-performance, motorsport and specialized applications. Select each component according to the requirements of the complete braking system.

Fitment & Compatibility
Read the specific GM model, year, drivetrain and brake notes in the table below. The G-Body-style factory disc spindle requires substantial machining: DS-1440 details removal of the original caliper ears and modification of bracket mounting holes. This work belongs with a qualified machine shop. Verify the spindle generation before comparing hub bearings; similar GM spindles are not automatically interchangeable. The +0.10-inch hub change affects wheel placement. Hoses must be sourced to the installed arrangement. A generic parking-cable note does not mean this front kit includes a parking brake.
