Wilwood Rear Drilled/Slotted Brake Package, FR-S/BRZ/86/GR86 (2013–2024), Black Four-Piston Calipers

This Wilwood rear conversion pairs black four-piston radial calipers with drilled/slotted 12.88-inch iron rotors on separate hats. The supported Scion, Subaru and Toyota applications retain their compatible original parking-brake arrangement. Application-specific rear hoses are included, while the condition and adjustment of the vehicle's parking components remain part of a correct installation. 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

Check the exact model/year entry before comparing the rear hubs and rotor-hat registration. A shared platform does not remove the need to identify original brake equipment. Inspect and adjust the existing parking mechanism, then align the hydraulic calipers using the bracket instructions. Compare the wheel's inner profile with the full clearance drawing. Brake hoses need freedom through suspension travel, and the completed rear package should be assessed against the front brakes and master-cylinder output.

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