Product details
This Wilwood adapter connects a backside-mount asphalt racing hub or GEN III Sprint inboard hub to a floating brake rotor. It combines a 5 x 4.875-inch hub mounting circle with an 8 x 7.00-inch rotor circle in hard-anodized aluminum. Wilwood Engineering’s disc-brake range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized systems. Bill Wood founded the company in 1977, and its base is Camarillo, California. Each part is chosen to suit the operating and installation requirements of the whole brake system.
