Product details
An anodized Wilwood XRS6R housing contains six differential-bore pistons in this right-hand configuration. The 1.62/1.12/1.12-inch sequence produces 4.04 square inches of effective area for a nominal 1.10-inch rotor-width assembly. 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 bore sequence and rotation before matching the 5.98-inch radial bracket. Brake balance depends on the hydraulic layout as well as the caliper's physical mounting, so vehicle identity alone is insufficient.
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.
