Product details
The 15.35-inch diameter and 1.42-inch section make this GT rotor a specific large-ring configuration. Its right-hand curved-vane design uses 60 vanes, with a twelve-hole mounting circle of 8.60 inches rather than the more common 8.75-inch dimension. Since its founding by Bill Wood in 1977, Wilwood has designed and manufactured disc brake systems from its base in Camarillo, California. Its products span rotors, calipers, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. Brake selection should account for the whole installation, including mounting dimensions, friction materials and hydraulic balance.
