Product details
The right-hand black Wilwood XRS6R is the 1.25-inch nominal rotor-width version with a 1.75/1.25/1.25-inch bore sequence. Its forged body and 5.98-inch radial centers address the mechanical interface, while the six-piston area determines its hydraulic requirements. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.
