Product details
This left-hand rear rotor carries its 12.19-inch SRP friction surface on an integral 2.320-inch-offset hat. The cast-in 7.24-inch parking drum and 0.81-inch ring must both agree with the installed brake package. Wilwood’s calipers, rotors, master cylinders, valves, fittings and lines support complete disc brake systems rather than an isolated component choice. Founded in 1977 by Bill Wood and based in Camarillo, California, the company designs and manufactures these systems for motorsport, street performance and specialized applications. Correct pairing of the rotor with its surrounding hardware is essential.
