Red Combination Parking Brake calipers and drilled/slotted 12.19-inch rotors form this Wilwood Civic Si rear brake package.

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.

Fitment & Compatibility

Verify the actual Civic Si rear assembly rather than transferring fitment from a front kit. DS820 sets out the mechanical cable connection and caliper adjustments; the parking lever must operate and release correctly. Suitable hydraulic lines are chosen separately. Wheel fit requires the full conditional 17-inch profile, with some 16-inch designs possible only when the template confirms space. Inspect the original hubs and establish caliper alignment before checking cable travel and testing both braking functions.

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