Product details
A four-on-4.50-inch stud clearance pattern distinguishes this low-profile rear casting. Its deeper 2.32-inch hat locates the plain 11.00-inch friction ring over the corresponding internal parking-brake assembly. Wilwood Engineering's disc brake systems are designed and manufactured for motorsport, street-performance and specialized applications. Founded in 1977 by Bill Wood and based in Camarillo, California, the company makes calipers, brake rotors, master cylinders, valves, fittings and brake lines. These individual parts must be chosen to work within the complete braking system.
