Wilwood Rear 11-Inch Drilled/Slotted Brake Conversion, Black CPB Calipers, Fiat 500 (2012–2015)

Black CPB calipers and drilled/slotted rotor faces distinguish this Wilwood rear conversion for the 2012–2015 Fiat 500 fitments listed below. Each 11-inch rotor bolts to a separate aluminum hat; the calipers combine hydraulic stopping with cable-operated parking action. BP-10 pads and the specified rear flex lines complete the friction and hydraulic connections for this selected configuration. 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 for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Read the individual hatchback, cabriolet, Abarth and other trim entries rather than assuming every 500 uses the same rear installation. Compare hat-to-hub fit and the 4 x 98 mm wheel pattern with the vehicle. Cable attachment, lever travel and freedom from drag must be established with the parking brake released. Use the wheel template to check clearance throughout the spoke and barrel envelope. The minimum wheel diameter alone cannot establish that a particular wheel will clear this assembly.

Match the individual year, model, submodel and equipment conditions in the fitment table below.
