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

This is the Brembo Rear GT Big Brake Kit for the 2023 and newer Toyota GR Corolla. It's a comprehensive upgrade designed to significantly improve your braking performance, especially during demanding driving conditions. The kit includes everything you need to install a robust 4-piston caliper system with large, two-piece rotors.

At the heart of this kit are the 4-piston calipers, forged from aluminum for a strong yet lightweight structure. These calipers house larger brake pads, which increase the contact area with the rotor for better heat dissipation and more consistent stopping power. The rotors themselves are a two-piece design, measuring 345mm in diameter and 28mm thick. This design helps reduce unsprung weight and allows for better thermal management compared to a single-piece rotor. The slotted surface on the rotors helps to sweep away dust and gas that can build up between the pad and rotor, maintaining optimal friction and preventing fade during hard braking. The black finish on the calipers adds a clean, performance-oriented look behind your wheels.

This kit is a substantial upgrade for GR Corolla owners looking to get the most out of their braking system. It's designed for direct fitment, meaning it bolts on without requiring modifications to your existing suspension or brake lines, though it's always a good idea to consult the manufacturer's installation guide for specific details. When installing a big brake kit like this, it's common practice to also consider upgrading your brake fluid to a higher temperature rating to fully take advantage of the increased thermal capacity of the new components.
