Product details
Black powder coat covers the forged housing of this left-hand Wilwood XRS6R. Its six stainless pistons use 1.62/1.12/1.12-inch bores, while the nominal 1.10-inch rotor-width bridge and internal passages complete the selected configuration. 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
Confirm that the caliper's left-hand designation suits the bracket and rotor direction. Check the 1.00–1.10-inch width allowance and wheel clearance without assuming all XRS6R variants share the same hydraulic area.
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.
