Brembo 23+ GR Corolla Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted TY3L - Yellow

This Brembo GT Big Brake Kit for the rear of your 2023 and newer Toyota GR Corolla includes everything you need to significantly upgrade your stopping power. You get a pair of yellow 4-piston Brembo GT calipers, two 345x28mm two-piece slotted rotors, and all the necessary hardware to get them installed. This kit is designed to be a direct fit for the GR Corolla, making it a straightforward way to improve your car's braking performance, especially for track use or spirited driving.

The calipers are cast aluminum, which keeps weight down while maintaining strength. The 4-piston design offers more clamping force than the factory setup, and the larger 345x28mm two-piece rotors provide a greater surface area for heat dissipation. The slots in the rotors help to vent gases and debris away from the pad surface, ensuring consistent braking performance even under heavy use. Brembo is well-known for their high-performance braking systems, and this kit represents their GT line, which is built for demanding applications where braking consistency and power are critical.

When installing a big brake kit like this, it's important to ensure you have the right tools and follow the manufacturer's instructions carefully. While this kit is designed as a direct bolt-on, it's a significant upgrade that can change the feel and performance of your braking system. Many owners find that upgrading the rear brakes in conjunction with front brake upgrades offers the most balanced and effective improvement.
