Wilwood Front SX6R Dynamic Brake Kit for Chevrolet Corvette/Corvette E-Ray C8 (2020–2025), Black Calipers and 15-Inch GT Slotted Rotors

SX6R six-piston front calipers pair with 15.00-inch rotors on separate dynamic lug-drive hats in this C8 Corvette package. Brake pads, mounting hardware and braided lines are included for the specified original hub/upright interface. Black calipers and 15.00-inch GT slotted rotors are the selected configuration. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, chosen to match the complete system.

Fitment & Compatibility

Check the exact Corvette entry: Stingray 2020–2025, Z06 2023–2025, Corvette E-Ray 1LZ 2024, and the listed 2025 E-Ray and ZR1 rows.
