Product details
The red right-hand Wilwood XRS6R combines a 1.25-inch nominal rotor-width bridge with six stainless pistons. Its 4.86-square-inch effective area and internal fluid passages are part of a defined configuration, suitable only when matched to the system's other brake components. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. It designs and manufactures disc braking systems for motorsport, street-performance and specialized applications, with a component range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
Check the right-hand caliper orientation and bore sequence before locating it ahead of or behind the spindle. Verify rotor offset and wheel clearance with the final bracket rather than relying on a family photograph.
With 20+ years of experience, PMB Performance can help assess the brake hardware. Provide the caliper number, rotor dimensions and bracket measurements when asking about compatibility.
