Product details
The left-hand GT rotor brings a slotted surface to the 12.88-inch, 0.81-inch-thick iron ring. Its curved-vane core and twelve-hole mounting flange identify the replacement, with the plain finish leaving the casting uncoated. Founded in 1977, Bill Wood’s Wilwood is based in Camarillo, California and designs and manufactures disc brake systems for motorsport, street performance and specialized applications. Its range runs from calipers and rotors to master cylinders, valves, fittings and lines. Choosing a rotor involves matching those surrounding components as well as the vehicle’s intended use.
