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.
