Wilwood Scalloped Drilled Steel Racing Rotor, 11.44 x 0.25-inch, Black Oxide

The scalloped outline reduces material around this thin 0.25-inch steel rotor. Drilled faces and black oxide finish identify the 11.44-inch configuration intended for selected drag or dirt racing duties rather than street service. The manufacturer is Wilwood Engineering of Camarillo, California, founded by Bill Wood in 1977. It designs and manufactures disc brake systems, supplying calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. Matching this component requires consideration of the complete brake system.
