Product details
The Wilwood C7 Corvette front hat uses a bobbin-mounted twelve-bolt rotor. Verify the exact model-year package and 0.518-inch offset before ordering. Bill Wood founded Wilwood Engineering in 1977, and the manufacturer is based in Camarillo, California. Wilwood designs and manufactures disc brake systems alongside calipers, master cylinders, rotors, fittings, brake lines and valves. The motorsport, street-performance and specialized ranges depend on components selected to work within a complete braking system.

Fitment & Compatibility
Use this replacement only within the specified Chevrolet Corvette C7 brake conversions. Compare the hub, caliper position and rotor attachment to the complete assembly drawing. Use the correct dynamic mounting hardware and rotor connection; an ordinary fixed-mount bolt set does not establish the specified floating assembly. The product-page application note extends C7 coverage to 2020, while other C7-specific Wilwood components end at 2019. Confirm the actual model year and Wilwood kit; this listing does not assert 2020 C8 compatibility.
