Fitment & Compatibility

For the listed 2020–2025 C8 Corvette applications, with separate year/trim entries for Stingray, Z06, E-Ray and ZR1. Confirm the original brake configuration and the wheel template for the particular car; the full model range does not imply that every trim appears in every year.

The supplied BP-30 pads are a high-temperature race compound. Extended use at low operating temperatures can cause premature rotor and pad wear; select the brake system and pad compound for the intended operating conditions. The kit includes the specified 24-inch hydraulic hose set. Follow the rotor assembly and bedding instructions, and verify brake balance before track use.
