Wilwood Front ProMatrix 14-Inch GT Rotor Kit for Chevrolet Corvette (2006–2013), C6 Z06/Grand Sport

Wilwood's front ProMatrix rotor package replaces the specified C6 Corvette Z06/Grand Sport iron discs with 14-inch GT slotted rings on aluminum hats. The Spec-37 rings have 72 curved vanes and retain the matched original six-piston calipers. This is a rotor-and-hat replacement assembly, so no calipers or brake pads are included and the existing brake system must meet the stated configuration. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Compare the installed OE rotor dimensions and caliper package with DS899 and the current application conditions. The selected manufacturer notes identify replacement of the 355mm factory iron rotor; carbon-ceramic or different-diameter brakes are not established as interchangeable. Verify wheel clearance and inspect the retained pads and calipers. Correct hub seating, runout and rotor direction remain necessary when fitting the two-piece assemblies.

Match the individual model, year, submodel and brake configuration in the fitment table below.
