Product details
For a left-side snap-ring brake assembly requiring factory preparation, this GT rotor supplies the burnished version of the 1.25-inch ring. The 48 curved vanes and slotted contact surfaces are supported by the same 7.18-inch lug-drive 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.
