Wilwood Red AERO4 Rear Brake Package with Drilled Rotors for Chevrolet Corvette C7, 14.25-Inch Rings and OE Parking-Brake Hats (2014–2019)

Red AERO4 calipers operate drilled-and-slotted 14.25-inch rotor rings in this C7 rear conversion. The iron hats work with the matched original parking-shoe assembly, keeping the mechanical parking function separate from the four-piston service calipers. Based in Camarillo, California, Wilwood Engineering was established by Bill Wood in 1977. It designs and manufactures disc brake systems, calipers, rotors, master cylinders, valves, fittings and brake lines. That range serves motorsport, street-performance and specialized applications; the individual parts must be matched to the requirements of the complete braking assembly.

Fitment & Compatibility

Review the listed Stingray, Z51, Z06, Grand Sport and ZR1 years and verify the installed parking-brake/hub arrangement. Check the DS1067 backing-plate and wheel-clearance instructions, then route the supplied rear flexlines without interference or strain.

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.
