Brembo 08-13 M3 (E90/E92/E93) Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Silver

This Brembo GT Big Brake Kit for the rear of your 2008-2013 BMW M3 (E90, E92, E93) includes everything you need to significantly upgrade your braking system. You get a pair of four-piston GT calipers, two 345x28mm two-piece rotors that are drilled for heat dissipation, and all the necessary hardware to get them installed. This kit is designed to replace your stock rear braking components with a more robust setup, offering improved stopping power and fade resistance, especially during spirited driving or track use.

The calipers themselves are cast aluminum, which keeps them strong yet relatively lightweight. They are designed to work with the included two-piece rotors, which feature a floating hat design. This allows for better thermal management as the rotor can expand and contract independently of the hub assembly. The drilled surface on the rotors helps to vent hot gases and moisture away from the pad surface, maintaining consistent braking performance even under heavy load. Brembo is a well-known name in braking, and this GT kit represents their commitment to high-performance braking solutions.

When installing a big brake kit like this, it's always a good idea to consult the manufacturer's installation guide for specific torque values and procedures. While this kit is designed as a direct replacement for the factory rear brake components, ensuring proper installation is key to achieving the performance benefits Brembo engineered into this system. You'll notice a more solid pedal feel and improved confidence when braking hard.
