Wilwood Drilled 14.25-Inch Front Disc Conversion for 2014–2019 Chevrolet Corvette C7, Black AERO6 Calipers and Aluminum Hats

The SRP configuration combines black AERO6 calipers with drilled-and-slotted 14.25-inch Spec-37 rotor rings. Its aluminum hats and supplied flexlines adapt the matched C7 front brake system while retaining the original hub arrangement specified for the kit. This is a Wilwood Engineering conversion package. Bill Wood founded the company in 1977, and it is based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, from calipers and brake rotors to master cylinders, valves, fittings and brake lines. Its motorsport, street-performance and specialized applications require each component to match the complete brake system.

Fitment & Compatibility

Review the complete Corvette submodel/year rows before choosing the conversion. Check the installed hub and brake equipment against DS1066 and allow the full caliper-to-wheel envelope. No replacement hub, master cylinder or booster is included.

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.
