Product details
This drilled steel rotor uses a dynamic mounting arrangement so its center interface is different from a conventional fixed bolted ring. The 12.90-inch solid disc is 0.38 inch thick and is intended for the specified drag or dirt racing assembly. Established in 1977 by Bill Wood, Wilwood develops its range around complete disc brake systems. The Camarillo, California manufacturer designs and manufactures calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. Installation geometry, pad selection and braking duty should be considered together when choosing this component.
