Wilwood Front SX6R Dynamic Conversion with 15-Inch Drilled/Slotted Rotors and Red Calipers, Chevrolet Corvette/Corvette E-Ray C8 (2020–2025)

SX6R six-piston front calipers pair with 15.00-inch rotors on separate dynamic lug-drive hats in this C8 Corvette package. Red calipers and 15.00-inch SRP drilled & slotted rotors are the selected configuration. Brake pads, mounting hardware and braided lines are included for the specified original hub/upright interface. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized systems, with selection governed by the complete brake installation.

Technical Details

• Check the wheel-clearance diagram before purchase; the nominal minimum wheel diameter is 19 inches.
• Connect the hydraulic line through the 1/8-27 NPT caliper inlet.
• This assembly leaves the documented wheel hubs in use. It supplies brake components rather than new hubs.

• Rotor mounting is through separate aluminum hats, offset 0.425 inch and finished in Type III anodize.
• Piston sizing follows the published 1.62, 1.12, 1.12-inch specification. The included brake-pad compound is BP-10.
• Caliper selection is 6-piston SX6R. Body finish: red powder coat; attachment: radial; piston material: stainless.

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. Match the actual factory brake package and upright; a trim name alone is not a substitute for checking the rotor/hat interface. The nominal minimum is 19 inches, with spoke clearance checked against the complete wheel drawing. The table below preserves the individual vehicle and brake-option entries; select the complete matching row before ordering.

With over 20 years of parts and application experience, PMB Performance can help compare this assembly with your existing brakes. Supply the hub, axle or spindle specification and wheel-clearance information before ordering.
