Brembo 23+ GR Corolla Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-1-Black

This Brembo GT Big Brake Kit for the 2023 and newer Toyota GR Corolla includes everything you need to significantly upgrade your rear braking system. You get a pair of Brembo 4-piston cast aluminum calipers, two 345x28mm two-piece slotted rotors, and all the necessary hardware for installation. This kit is designed to replace your factory rear brake components with a more robust and higher-performing setup, offering a notable improvement in stopping power and heat management.

The calipers are constructed from cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the 4-piston design. This piston count allows for more even pressure distribution across the brake pad surface, leading to more consistent and powerful braking. The rotors are a two-piece design, featuring a cast iron friction ring bolted to an aluminum hat. This construction helps reduce weight and allows for better thermal management, as the aluminum hat can dissipate heat more effectively than a solid cast iron rotor. The Type-1 slots on the rotor surface are engineered to help vent gases and dust away from the pad surface, maintaining optimal friction and preventing fade during aggressive driving or track use.

Installing a big brake kit like this is a significant upgrade for any GR Corolla owner looking to push their car's performance limits. While it's a more involved installation than simply swapping pads or rotors, the benefits in terms of braking performance, heat resistance, and overall feel are substantial. This kit is a solid option for drivers who frequently track their vehicle or demand the best possible braking performance from their GR Corolla.
