Wilwood Engineering has designed and manufactured disc brake systems since Bill Wood founded it in 1977. Its Camarillo, California operation supplies calipers, master cylinders, brake rotors, valves, fittings and lines for specialized, street-performance and motorsport applications. Each component must be chosen to match the complete brake system.

Fitment & Compatibility

Keep the Corvette C7 year/trim limits separate: Stingray is listed for 2014–2019, Z51 for 2014–2016, Z06 for 2015–2019, Grand Sport for 2017–2019 and ZR1 for 2019. Do not assign a later trim to the entire 2014–2019 span. SX6R six-piston calipers use 14.00 × 1.25-inch dynamic lug-drive rotor rings and separate hard-anodized aluminum hats. Slotted versions use ProMatrix pads; drilled-and-slotted versions use BP-10. Front hose kit 220-9100 is included, and DS-1338 requires enlarging the original hose-bracket opening to 0.625 inch. Check the original brake configuration, hub attachment and actual wheel with the 18-inch minimum guidance and clearance drawing.

Listed models: Corvette. See the supplied table below for each year, submodel and equipment condition.
