Wilwood Red Four-Piston Front Brake Kit, 11-Inch Drilled/Slotted Rotors for GM and Ridetech Pin Spindles

Red powder-coated Dynapro calipers, drilled-and-slotted rotors and replacement hubs form this front brake assembly. Its dust-boot piston protection and 11-inch rotor package are specified together for the documented spindle applications. Founded in 1977 under Bill Wood, Wilwood Engineering operates from Camarillo, California. The company designs and manufactures disc braking systems and components, including calipers, master cylinders, brake rotors, fittings, valves and brake lines. Its motorsport, specialized and street-performance range requires individual parts matched to the complete braking arrangement.

Fitment & Compatibility

Confirm the precise original or Ridetech pin spindle, including any machining described in DS998. The published hub offset changes the wheel position; also compare wheel-pad contact and the separate hose connections.

The installation reference distinguishes wheel-pad overhang from a supported stamped steel wheel. Overhang requires a 0.20-inch-thick steel spacer, 6.60 inches in diameter, part 300-11961 (listed in the installation parts list). A stamped wheel without overhang should instead use the separate 0.09-inch-thick, 6.15-inch-diameter shield 300-10716.

Flexible brake lines are not included. Original lines are not assumed to connect to the Wilwood calipers; select the application-specific or correctly sized universal hose and matching fittings.

Universal Flexline kits available: 220-7056 (14"), 220-7699 (16") or 220-8307 (18"). Choose correct length for your application.

An independently added universal parking-brake cable system may require cable or vehicle modifications. It is separate from this front service-brake kit.
