Product details
This coated GT rotor retains the thick 1.25-inch section of the right-hand 14-inch brake package. Black electro-coat accompanies the slotted faces and 72 curved vanes without changing the twelve-hole mounting geometry. 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.
