Brembo 23+ GR Corolla Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Black HA

This is the rear big brake kit from Brembo, specifically for the 2023 and newer Toyota GR Corolla. What you get in this box are the components to significantly upgrade your rear braking system. This kit includes a pair of four-piston aluminum calipers, two-piece 345x28mm rotors that are drilled for heat dissipation, and all the necessary hardware to get them installed. It’s designed to give your GR Corolla a substantial improvement in stopping power and heat management, especially during spirited driving or track use.

Brembo is well-known for its high-performance braking components, and this kit is no exception. The calipers are cast aluminum, which keeps weight down while providing a solid foundation for the four pistons. These pistons work together to apply even pressure across the larger 345x28mm rotors. The two-piece rotor design is a notable feature; it separates the braking surface from the hat, allowing for better thermal expansion and contraction without warping. The drilled surface on the rotors helps to vent gases and heat away from the pad surface, which is crucial for maintaining consistent braking performance when things get hot. This kit is a direct upgrade, meaning it's designed to fit without requiring major modifications to your GR Corolla's suspension or chassis.

When you're looking to get the most out of your GR Corolla's performance, especially on the track or during demanding driving conditions, a robust braking system is key. This Brembo kit addresses the rear braking system, complementing any front upgrades you might have or plan to do. Make sure to consult the manufacturer's installation guide for specific torque values and any required brake fluid types for optimal performance and safety.
