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

Brembo is a name many people trust when it comes to stopping power, and they're known for making high-performance brake components. This rear Big Brake Kit (BBK) is built specifically for the 2023 and newer GR Corolla, giving you a significant upgrade over the factory setup. If you're looking to improve your car's braking performance, especially for track days or spirited driving, this kit is designed to handle the heat and provide more consistent stopping power.

This kit features a 4-piston caliper design, which means more clamping force on the rotor compared to a standard 2-piston caliper. The rotors are a 2-piece design, measuring 345x28mm, and they're drilled to help dissipate heat and reduce weight. The 2-piece construction also allows for better thermal management as the hat can expand and contract independently of the braking surface. These rotors are drilled, which helps with cooling and can also help clear out brake dust and gas under heavy use. The calipers are cast aluminum, offering a good balance of strength and weight savings, and they come in a black finish to look sharp behind your wheels.

When installing a kit like this, you're getting a comprehensive package designed to work together. The calipers, rotors, and mounting hardware are all part of the system. It's a good idea to check the manufacturer's installation guide for specific details, but this kit is designed to be a direct replacement for the rear braking system on the GR Corolla. You'll likely notice improved pedal feel and more confidence when braking hard, whether on the street or at the track.
