Wilwood Rear RZR Pro R/Turbo R Race Package (2022–2024) — Plain 11.25-Inch Lug-Drive Rotors, Anodized NDPR & BP-28

This five-lug RZR rear race package combines plain 11.25-inch steel rotors with four-piston NDPR calipers in a Type III anodized finish. BP-28 pads distinguish the race specification; the rotor remains a solid, plain-face design. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are all part of Wilwood Engineering’s range of disc brake systems and components. The Camarillo, California company was founded in 1977 by Bill Wood and designs and manufactures these products for motorsport, street-performance and specialized applications. Compatibility with the complete brake system determines the appropriate component choice.
