Product details

The red left-hand Wilwood XRS6R combines a 4.04-square-inch effective piston area with a nominal 1.10-inch rotor width. Internal fluid ports link the opposing banks, and the radial mount allows its alignment to be established through the correct caliper bracket. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components. Bill Wood founded the company in 1977; its motorsport, street-performance and specialized range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines.
