Product details
Red Superlite six-piston calipers clamp GT slotted 12.88-inch rotors in this Wilwood front hub kit. Separate hats and aluminum replacement hubs are supplied for the specified GM disc-spindle arrangement. The conversion retains the original spindle after preparation and uses its stated OE wheel-position reference. 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
Identify the original 11-inch rotor spindle and match the vehicle's model/year row before ordering. DS610 describes the necessary spindle modifications and caliper alignment. Provide hydraulic lines with the proper fittings and routing for the car. Check the full wheel drawing because a nominally unchanged offset does not establish clearance for the new caliper body.
Match the individual model, year, submodel and brake configuration in the fitment table below.
