Wilwood Rear Left Dual-Pattern SRP Rotor and Hat, Black 12.19 x 0.81-inch

For the left rear position, this SRP casting retains the dual five-lug clearance pattern and 1.91-inch offset. The black-coated drilled-and-slotted ring is part of a disc/drum system that still requires the appropriate parking shoes, brackets and axle registration. Disc brake systems and components are the work of Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. The company designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications, with each component selected to match the complete system.

Fitment & Compatibility

Check the rear disc/drum kit's 1.91-inch offset and 7.24-inch parking drum as well as the selected five-on-4.50- or five-on-5.50-inch stud circle. Its 3.06-inch center can use separately selected register adapters in Wilwood's specified 2.00–2.86-inch range; the rotor does not convert the hub's wheel pattern.
