Product details
Red six-piston calipers pair with SRP drilled/slotted rotors in this Wilwood Magnum Force front conversion. The 12.88-inch one-piece rotor layout uses replacement hubs, bearings and the specified brackets, with BP-10 pads included. It is selected by the installed drop-spindle configuration rather than an assumed vehicle-model application. 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. Its product range serves motorsport, street-performance, and specialized applications, with individual components selected to match the requirements of the complete brake system.

Fitment & Compatibility
Use DS866 to inspect the upright and compare the mounting arrangement before disassembly. Verify that the hub bearings and wheel pattern agree with the chosen components and that the calipers can be centered over the rotors. Hydraulic flex lines are additional and must clear moving suspension and steering parts. Measure the intended wheel against the full conditional 17-inch profile. A wheel with sufficient diameter can still lack room behind its spokes for the six-piston caliper.
