Wilwood Front 15-Inch SRP Drilled/Slotted Brake Kit, Chevrolet Corvette/Corvette E-Ray C8 (2020–2025) with Black SX6R Dynamic Calipers

Black calipers and 15.00-inch SRP drilled & slotted rotors are the selected configuration. 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. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Each component must suit the surrounding brake system.

Technical Details

• The Wilwood manufacturer part number is 140-17004-D. This product is sold as a kit.
• The black powder coat caliper bodies are SX6R units with 6 pistons. Stainless pistons and radial mounts are specified.
• 15.00-inch rotors are supplied in the SRP drilled & slotted configuration; the published thickness is 1.25 inch. These rotors use Spec-37 Iron.
• Friction material supplied is BP-10; the caliper bore measurements are 1.62, 1.12, 1.12 inches.
• A 0.425-inch hat offset locates each rotor ring. Hats use aluminum construction and Type III anodize finish.

• The original hub arrangement must be retained or provided separately. No replacement wheel hubs come with the kit.
• Caliper inlet thread is 1/8-27 NPT.
• Published minimum rim diameter is 19 inches. Use the template to check spoke clearance as well.

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. Read the fitment table below for the exact year and option combination; do not apply one row's restrictions to another vehicle.

For help selecting the correct brake package, give PMB Performance the vehicle details and measurements of the installed hardware. Our 20+ years of parts experience help resolve fitment beyond a model name alone.
