Wilwood Front Black Six-Piston Conversion for C7 Corvette, 15-Inch Drilled-and-Slotted Brake Rotors — Selected 2014–2019 Applications

The black AERO6 configuration provides drilled-and-slotted 15-inch front rotors for the specified C7 hub. A six-piston radial caliper design and two-piece rotor assembly replace the matching original service brakes. Bill Wood’s 1977 founding of Wilwood Engineering began a disc brake design and manufacturing business based in Camarillo, California. The range includes master cylinders, calipers, rotors, brake lines, valves and fittings for motorsport, street-performance and specialized vehicles. Component selection must consider the complete braking arrangement.

Fitment & Compatibility

Check the individual C7 Stingray, Z51, Z06, Grand Sport or ZR1 year entry and the existing hub before installation. DS-1091 includes flexline kit 220-9100 and requires the original hose-bracket opening to be enlarged as detailed in the guide. The two listed hat patterns describe the supplied hardware; use only the pattern matching the actual wheel hub. Compare wheel spokes and barrel with the 15-inch assembly template.

Listed models: Corvette. Use the fitment table below for the individual years, submodels and equipment conditions.
