Brembo 08-14 WRX STI Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Black

This is the Brembo Rear GT Big Brake Kit for your 2008-2014 Subaru WRX STI. If you're looking to significantly upgrade your braking performance, especially for track days or spirited driving, this kit is designed to handle the heat and demands of hard braking. It replaces your factory rear brake setup with a much more robust system, featuring larger rotors and powerful calipers.

At the heart of this kit are the 345x28mm two-piece, drilled rotors. The two-piece design helps manage heat more effectively by allowing the rotor hat to expand and contract independently from the friction surface, which can reduce the risk of warping. Drilling the rotors helps dissipate heat and gases, keeping your brakes cooler and providing a more consistent bite, especially during prolonged braking events. The calipers are a cast 4-piston design from Brembo, known for their solid construction and ability to apply even pressure across the brake pads. This setup is built to work together, offering improved stopping power and better fade resistance compared to stock components.

This kit includes everything you need to install the rear big brake system. You'll find the calipers, the two-piece rotors, brake pads, and all the necessary mounting hardware. While this is a comprehensive kit, it's always a good idea to consult the manufacturer's installation guide for specific torque values and any recommended break-in procedures to get the most out of your new Brembo brakes.
