Product details
The wide 10.75-inch twelve-bolt flange defines this right-hand 16-inch GT rotor. Its Spec-37 ring uses a 1.38-inch section and 60 curved vanes, with a 10.00-inch center register and black electro-coat finish. 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.
