Wilwood Right Black SRP Rotor, 12.19 x 1.10-inch, Eight on 7.00-inch Mount

For a right-side system using a separate eight-bolt hat, this SRP rotor supplies the 12.19 x 1.10-inch iron ring. Its 6.45-inch registration and 0.323-inch mounting holes are part of the fit, not interchangeable details. 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 1.10-inch working width must suit the caliper, while the hat centers the ring on its 6.45-inch register. Check the 8 x 7.00-inch attachment and radial pad coverage before installation. Vehicle make or wheel pattern alone cannot identify a replacement rotor ring. Wilwood specifies the SRP face treatment for street and moderate-temperature race duty; severe sustained racing calls for evaluation of the corresponding HD or GT option.
