Product details
Black powder coat finishes this left-hand Wilwood XRS6R for the 1.10-inch nominal rotor-width arrangement. The forged body houses six differential pistons with 4.86 square inches of effective area and retains the X-shaped bridge across the pad opening. 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
Use the 11.75–14.00-inch rotor envelope as a dimensional check, not a chassis-fit guarantee. The bracket must establish the correct height and offset while preserving hose, wheel and bleed-screw clearance.
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.
