Wilwood Front SRP Rotor Conversion, Honda Civic 2006–2015 and CR-Z 2011–2015, Black Six-Piston Calipers

Drilled/slotted 12.88-inch SRP rotors distinguish this black-caliper Wilwood Honda front package. The six-piston Superlite design works with BP-10 pads and a separate-hat rotor assembly, leaving the original hubs in service. The caliper brackets and ring dimensions are chosen for the Civic/CR-Z applications individually listed below. 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

Verify the exact Honda trim and year, then check its factory front brake and hub arrangement against DS819. Later Civics retain the original line/ABS bracket and may need its mounting hole enlarged for the replacement flexline fitting. The hose kit is separate, and one line selection cannot be assumed for every listed car. Use the wheel-clearance drawing to establish spoke depth and barrel fit; a nominal 17-inch size is only conditional. Set rotor runout and caliper centering before testing.

Check the individual year, model, submodel and equipment conditions in the fitment table below before ordering.
