Wilwood XRZ Radial Mount Pads, BP-35 Racing, Four Pieces

Established by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. The company designs and manufactures disc brake systems for motorsport, street and specialized applications, producing calipers and brake rotors along with master cylinders, valves, fittings and hydraulic lines. BP-35 brake pads in the .80-inch XRZ4R configuration supply four replacement pads. Each part must be selected to work with the complete brake system and its requirements.

The .80-inch XRZ4R selection pairs the thicker radial-caliper pad with BP-35. For iron or steel race rotors, this formulation develops high friction with a progressive temperature response and smooth release. It is a racing pad, not a street compound, and should be selected with the car’s brake balance and operating heat in mind.

Fitment & Compatibility

Select this 0.80-inch pad for the XRZ4R radial-mount caliper. It is thicker than the 0.65-inch XRS version; verify the available pad space and rotor specification.
