Wilwood Left 12.88-inch Black SRP Rotor, One-Inch Width, Drilled and Slotted

This left SRP ring combines a 12.88-inch diameter with a 1.00-inch working width. The directional face treatment and black coating identify its configuration, while Wilwood's heavier-duty HD or GT choices should be considered for sustained severe race duty. Based in Camarillo, California, Wilwood Engineering was founded in 1977 by Bill Wood to design and manufacture disc brake systems and components. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications. Rotor selection is therefore a decision about the whole brake system and its mating parts.

Fitment & Compatibility

The left SRP ring fits a system designed for 12.88-inch diameter and 1.00-inch rotor width. Its 8.25-inch register must center on a hat carrying twelve fasteners on an 8.75-inch circle. Wilwood specifies moderate-temperature street or race duty for this drilled face; evaluate HD or GT construction for sustained severe competition.
