20-26+ C8 Corvette 4-Piston Rear Caliper/Rotor Combo (390x29mm) - Alcon

Fits 2020+ C8 Corvette

Description:

Alcon Pro‑System Rear Brake Kit for C8 Corvette — the performance rear brake upgrade engineered for the 2020+ C8 Corvette. This Pro-System rear brake kit (Part Number BRK.200521) is built for enthusiasts seeking improved braking performance, thermal control, and race-bred stopping power over the factory rear setup.

Designed with precision in Mooresville, North Carolina, this rear system features fully floating 390 × 29 mm rotors machined from specially formulated grey cast iron for superior heat dissipation, friction stability, and long-lasting performance. Dyno-bedded rotors and high-performance pads are included to ensure optimal pad-to-rotor contact and out-of-the-box performance — no extra bedding steps required. The kit’s fully floating rotor design with anti-rattle clips enhances durability and quiet operation, while precision-machined aluminum hats reduce unsprung weight and improve reliability under demanding conditions.

Paired with forged aluminum 4-piston calipers, this rear brake upgrade delivers consistent brake modulation, enhanced heat management, and greater stopping force compared to stock brakes. The calipers feature aerospace-grade construction with high-temperature seals and stainless-steel pistons, offering track-inspired consistency and strength. Designed to retain the Corvette’s parking brake function and fit both OEM 20″ wheels and compatible aftermarket wheels, the BRK.200521 kit elevates rear braking confidence for street driving, high-performance events, and track days.

Whether paired with upgraded fronts or as part of a complete brake system overhaul, this Alcon rear big brake kit brings motorsport-grade performance and reliability to your C8 Corvette rear axle.
