Wilwood Rear 14.00-Inch SRP Rotor & AERO4/MC4 Caliper Kit, Black, Custom C7-Upright Chassis

Wilwood configures this rear AERO4/MC4 kit around 14.00 × 1.10-inch rotors for C7 Front Uprights on Custom Rear Chassis. The selected black calipers use 4 service pistons each; matching the factory or specified conversion hardware is essential to the complete installation. Camarillo, California is home to Wilwood Engineering, founded in 1977 by Bill Wood. The company designs and manufactures disc-brake systems for motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must match the complete braking system.

Fitment & Compatibility

DS1528 documents a C7 Corvette front upright used at the rear of a custom chassis. Verify the Roadster Shop Fast Track IRS arrangement and exact upright, hub register, stud pattern and 18-inch wheel clearance; this is not a stock C7 rear-brake replacement. The MC4 is a separate mechanically actuated parking caliper. Plan compatible cable actuation and separate hydraulic hoses.
