Brembo 04-10 5-Series (Excl. xDrive/M5) Rear GT BBK 4 Pist Cast 345x28 2pc Rotor Slotted Type1-Red

If you're looking to significantly upgrade the stopping power on your 2004-2010 BMW 5-Series (excluding xDrive and M5 models), this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit replaces your factory rear brake components with a much larger and more robust setup, designed to handle higher thermal loads and provide more consistent braking performance, especially during spirited driving or track use.

At the heart of this kit are the 4-piston cast aluminum calipers, which offer increased clamping force over the stock calipers. These calipers grip large 345x28mm two-piece rotors. The two-piece design allows the rotor and hat to expand and contract independently, which can help reduce the risk of rotor warping under extreme heat. The rotors themselves are slotted, with Brembo's Type 1 slot pattern. These slots help to sweep away dust and gas that can build up between the pad and rotor surface, maintaining a cleaner contact patch and improving braking consistency. The calipers are finished in a striking red powder coat, adding a visual upgrade to your vehicle.

This kit is designed as a direct replacement for the specified 5-Series models, meaning it bolts on without requiring extensive modifications. It includes everything you need to install the rear big brake system, including the calipers, rotors, mounting brackets, and brake lines. While this kit is a significant upgrade, it's always a good idea to ensure your front brakes are also up to the task, or consider a matching front kit for a balanced braking system. Refer to the manufacturer's installation instructions for detailed guidance.
