Brembo 23+ GR Corolla Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Silver

The cast aluminum calipers in this Brembo rear big brake kit are designed with four pistons, each measuring 34mm, to provide strong clamping force on the 345x28mm two-piece rotors. This setup is specifically for the 2023 and newer Toyota GR Corolla, offering a significant upgrade over the factory braking system. The two-piece rotor design helps manage heat more effectively by allowing the rotor and hat to expand independently, reducing the risk of warping under heavy use. These rotors are drilled, which helps to dissipate heat and gases, contributing to more consistent braking performance, especially during spirited driving or track use.

Brembo's reputation in high-performance braking is built on decades of experience, and this kit reflects that. The calipers are not just about stopping power; they are also engineered for durability and heat resistance, crucial for sustained performance. The 345mm diameter rotors offer a larger surface area for the brake pads to engage with, further improving stopping capability. Installation involves replacing your stock rear brake components with these upgraded parts, and it's recommended to consult the manufacturer's instructions for the proper procedure to ensure optimal performance and safety. This kit is a substantial investment in your GR Corolla's performance, focusing on enhancing the rear braking bias and overall thermal capacity.

When installing this kit, ensure you have the necessary tools and knowledge for brake system work. It's also a good idea to consider upgrading your brake fluid to a higher temperature rating to take full advantage of the increased thermal capacity of this big brake kit. This rear kit is designed to work in conjunction with your existing front brakes, but for a complete system overhaul, consider matching it with a high-performance front brake setup. The silver finish on the calipers and the drilled rotors give a clean, performance-oriented look behind the wheels.
