Product details
Black six-piston Superlite calipers and 14-inch drilled/slotted rotors make up this Wilwood GM front conversion. Replacement hubs and separate hats locate the vented Spec-37 friction rings on the specified disc spindle. A matching model name does not substitute for confirming that spindle's original rotor arrangement. 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
Check the applicable GM row and the OE 11-inch-rotor spindle before installation. DS611 details the required spindle modifications and alignment procedure. Wheel clearance must be checked with the diagram for this 14-inch package, including spoke depth. Hydraulic flex lines are separate, while the existing master cylinder should be assessed for system displacement and brake balance.
