Wilwood Rear Left Black SRP Rotor with Blank Hat, 11.00 x 0.81-inch

This left-hand blank-hat rotor offers the SRP hole-and-slot treatment on the braking ring while leaving the wheel-stud pattern unfinished. Its 1.91-inch offset and 7.24-inch internal drum are fixed dimensions for the matching rear conversion. The broader Wilwood range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California, designing and manufacturing disc brake systems for motorsport, street-performance and specialized applications. Individual components must be coordinated with the complete braking system.

Fitment & Compatibility

This blank-pattern 11.00-inch rear rotor requires professional machining of the correct stud-clearance pattern before installation. Confirm the 1.91-inch offset, 3.06-inch registration and internal drum against the low-profile rear brake kit. Optional register adapters are available separately for specified 2.00–2.86-inch axle registers.
