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

If you're looking to significantly improve the braking performance of your 2023 and newer Toyota GR Corolla, especially for track days or spirited driving, this rear Big Brake Kit from Brembo is a serious consideration. This kit replaces your factory rear brake setup with larger, more capable components designed to handle increased heat and provide more consistent stopping power. The calipers are a robust 4-piston cast iron design, paired with substantial 345x28mm two-piece slotted rotors. The black finish on the calipers adds a clean, performance-oriented look behind your wheels.

Brembo is well-known for its high-performance braking systems, and this kit is built to match that reputation. The 4-piston calipers offer increased clamping force over the stock units, which translates to better pedal feel and shorter stopping distances. The two-piece rotor design helps manage heat more effectively; the floating hat allows the rotor ring to expand and contract independently, reducing the risk of warping. Slotted rotors are chosen for their ability to help clear away brake dust and gasses that can build up between the pad and rotor surface, maintaining optimal friction and preventing fade under heavy use. This kit is designed as a direct replacement for the rear axle, aiming for a straightforward installation process, though professional installation is always recommended for brake system upgrades.

When upgrading your braking system, it's important to consider the entire vehicle. While this kit focuses on the rear, you may want to evaluate your front brakes to ensure a balanced system. This Brembo kit includes everything needed for the rear axle installation, including the calipers, rotors, and necessary hardware, allowing you to get your GR Corolla stopping with confidence.
