Wilwood Rear AERO4 Disc Conversion with OE Parking-Brake Hats, Black Four-Piston Calipers and 14.25-Inch GT Rotors for Selected Chevrolet Corvette C7 (2014–2019)

This Corvette C7 rear package uses black AERO4 calipers and 14.25-inch GT rotor rings on iron parking-brake hats. The hats retain the specified original mechanical parking assembly, while the four-piston calipers and BP-20 pads provide the hydraulic service brakes. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California. It designs and manufactures disc brake systems and components serving motorsport, street-performance and specialized applications. The range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines; their individual specifications must be matched to the complete brake system.

Fitment & Compatibility

Match the exact Corvette submodel/year row and the factory parking-brake interface below. DS1067 defines the rear hub, backing-plate and wheel-clearance requirements. The kit supplies rear flexlines but does not replace the original hub or complete parking-shoe mechanism.

The application includes specified Stingray, Z51, Z06, Grand Sport and ZR1 rows within 2014–2019; verify each trim's individual year range and original brake equipment. A shared C7 body designation does not establish compatibility with every factory brake package.

Use the fitment table below for the complete model, year, submodel and brake-option conditions; every listed condition must match the installed vehicle.
