Product details
A larger 12.19-inch perimeter distinguishes this scalloped steel ring from the 11.75-inch version. It retains the thin 0.35-inch section, drilled friction face and black-oxide finish used in the specified drag or dirt racing brake arrangement. Wilwood began in 1977 with founder Bill Wood and is based in Camarillo, California, where it designs and manufactures disc brake systems. Calipers and rotors sit alongside master cylinders, valves, fittings and lines in a range serving motorsport, street performance and specialized applications. Selecting these parts together is essential to a correctly matched brake installation.
