Brembo 96-05 550/575 (Excl. GTC) Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Drilled- Yellow

The 380x28mm two-piece rotors in this Brembo GT Big Brake Kit are cast iron, chosen for their ability to handle heat and provide a solid foundation for braking performance. This kit is specifically designed for the rear of 1996-2005 BMW 550i and 575 models, excluding the GTC variant, and brings Brembo's renowned GT braking system to your vehicle. It features a four-piston caliper design, which allows for more even pad pressure across the rotor surface compared to smaller, single-piston calipers. This results in more consistent and powerful braking, especially under demanding conditions.

The calipers themselves are a cast aluminum construction, offering a good balance of strength and weight savings. They are finished in a bright yellow powder coat, adding a distinctive visual element to your wheels. The two-piece rotor design is notable because it allows the rotor ring to expand and contract independently of the caliper mounting hat. This helps to reduce the risk of rotor warping and can make replacement easier down the line, as only the rotor ring typically needs to be replaced. The rotors are drilled, which helps to dissipate heat and gasses, keeping the pads biting effectively even during repeated hard stops.

This kit includes everything you need to upgrade your rear braking system to a high-performance level. You'll find the four-piston calipers, the 380x28mm two-piece drilled rotors, and all the necessary mounting hardware and brake lines to complete the installation. While this kit offers a significant performance improvement, it's important to follow the manufacturer's installation instructions carefully, as proper setup is crucial for optimal function and safety. You may also want to consider upgrading your brake fluid to a higher temperature rating to take full advantage of the kit's capabilities.
