Wilwood Front Brake Kit with Red SX6R Calipers and 15-Inch SRP Rotors for Corvette C7, Listed 2014–2019 Applications

Red powder-coated SX6R calipers sit over drilled/slotted Spec-37 iron rotors in this C7 front brake package. Its 15.00 × 1.25-inch rotor specification, BP-10 pad compound and supplied flexlines define the configuration being ordered. The larger radial caliper and dynamic hat assembly need clearance inside the chosen wheel, even when the nominal wheel diameter meets Wilwood's 19-inch recommendation. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. It designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. This kit is one configuration within that disc-brake-system range and must be matched to the vehicle build.

Fitment & Compatibility

The application rows distinguish Corvette Stingray 2014–2019, Z51 2014–2016, Z06 2015–2019, Grand Sport 2017–2019 and ZR1 2019. Confirm the exact entry and factory spindle/hub arrangement. The installation sheet requires opening the original hose-bracket hole to 0.625 inch and checking the wheel template. Wilwood specifies compatibility with the original master-cylinder output and ABS; evaluate front/rear balance after the conversion. Use the complete application table below for the individual year, submodel, brake configuration and note attached to each entry.

With over 20 years of parts and fitment experience, PMB Performance can help compare the required mounting interface with the vehicle build. Share spindle or axle measurements and wheel information before ordering if anything is uncertain.
