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

If you're looking to significantly upgrade the braking performance of your 2023 and newer Toyota GR Corolla, this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit is designed to handle the demands of spirited driving and track use, offering improved stopping power and heat management over the factory setup. It's a comprehensive package that replaces key components of your rear braking system to deliver a more robust and reliable performance.

At the heart of this kit are the 4-piston cast aluminum calipers, finished in a striking yellow, which provide increased clamping force for better braking. These calipers work with substantial 345x28mm two-piece rotors. The two-piece design helps manage heat more effectively by allowing the rotor and hat to expand independently, reducing the risk of warping. The rotors themselves are slotted with Brembo's Type-1 pattern, which helps to sweep away dust and gas that can build up between the pad and rotor surface, ensuring consistent contact and improved braking performance, especially under heavy use. The cast aluminum construction of the calipers makes them strong yet relatively lightweight, contributing to overall vehicle dynamics.

This kit includes everything needed to upgrade your rear brakes, ensuring a cohesive system. When installing a big brake kit like this, it's always recommended to consult the manufacturer's installation guide for specific procedures and torque specifications. While this kit focuses on the rear, it's part of a performance upgrade that often pairs well with front brake system enhancements for a balanced braking feel.
