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

If you're looking to significantly upgrade the braking performance on your 1996-2005 BMW 550i or 575i (excluding GTC models), this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit is designed to handle the demands of spirited driving and track use, offering a substantial improvement over the stock braking system. It's all about giving you more confidence when you need to slow down quickly and repeatedly.

At the heart of this kit are the four-piston calipers, which provide more clamping force than typical two-piston setups. These calipers work with large 380x28mm two-piece rotors. The two-piece design helps manage heat by allowing the rotor and hat to expand independently, reducing the risk of warping. The rotors themselves are drilled, which helps to dissipate heat and gasses, keeping the pads in better contact with the rotor surface for consistent stopping power, especially under heavy use. The cast aluminum calipers are well-built and finished in a silver powder coat for durability and looks.

This kit includes everything you need to get these high-performance brakes installed, including the calipers, rotors, caliper mounting brackets, and brake lines. While this is a bolt-on kit, it's a complex installation that requires careful attention to detail. You'll want to ensure you have the proper tools and a good understanding of brake systems, or consider having a professional mechanic handle the installation. Upgrading to a big brake kit like this often pairs well with a corresponding front kit for balanced braking performance across the entire vehicle.
