Disc brake design and manufacturing extend across calipers, brake rotors, master cylinders, valves, fittings and brake lines. Parts for street-performance, specialized applications and motorsport must be selected to meet the requirements of the complete brake system.

Fitment & Compatibility
Check the existing Chevrolet Corvette C7 2014–2019 brake conversions against the dimensions above. The hub flange and rotor attachment are separate interfaces and both must match the intended brake package. Use the specified lug-drive friction ring and clip/snap-ring retention system. A conventional bolt-on ring is a different attachment arrangement.
