Product details
This right-hand rear rotor brings the SRP drilled-and-slotted face to Wilwood’s 11-inch low-profile disc/drum geometry. A black electro-coat finish covers the casting, whose integral hat retains the 1.910-inch offset required by the matching package. Camarillo, California is home to Wilwood, founded by Bill Wood in 1977. The company designs and manufactures disc brake systems for motorsport, street performance and specialized applications, supplying rotors, calipers, master cylinders, valves, fittings and lines. Matching the rotor to the complete assembly matters as much as selecting its diameter or surface treatment.
