Wilwood Rear SRP Rotor/CPB Conversion, Honda Civic Si 2006–2015, Black Hydraulic-and-Cable Calipers

SRP drilled/slotted rotors and black combination calipers distinguish this Wilwood Honda Civic Si rear conversion. Each caliper has one 1.34-inch piston and a mechanical parking lever, keeping the service and parking functions in the same assembly. The 12.19-inch rings mount on separate hats with BP-10 pads included. 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

The Civic must have the matching Si rear-disc layout described in DS820. Check the cable end, mechanical lever travel and hose routing as distinct installation tasks. Compare both spoke clearance and barrel clearance with the drawing before assuming the kit fits a wheel; the catalog's 17-inch minimum is conditional, and selected 16-inch designs need measurement. Retain only sound original hubs and verify the hat registration. Drum-brake Civics are not established applications for this rear package.

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