Product details
This Wilwood C10 front hat is associated with CPP spindles. Its 1.620-inch offset and twelve-bolt rotor interface require the matching brake kit. Bill Wood founded Wilwood Engineering in 1977, and the manufacturer is based in Camarillo, California. Wilwood designs and manufactures disc brake systems alongside calipers, master cylinders, rotors, fittings, brake lines and valves. The motorsport, street-performance and specialized ranges depend on components selected to work within a complete braking system.

Fitment & Compatibility
Wilwood DS649 identifies this hat in its C10 front kit for specified Classic Performance Products (CPP) drop spindles. Match the exact CPP spindle, hub, rotor and caliper package before ordering. The component page transposes the spindle initials to CCP; the assembly instructions identify CPP. This hat does not establish compatibility with an original spindle or another drop-spindle design. Select the rotor and attachment hardware separately for the documented assembly. Follow the installation drawing for engagement and clearance at every mounting point.
