Brembo 04-10 5-Series (Excl. xDrive/M5) Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Silver

If you're looking to significantly improve your 2004-2010 BMW 5-Series rear braking performance, especially if you've upgraded other components or plan on spirited driving, this Brembo GT Big Brake Kit is a serious consideration. This kit is designed to replace your stock rear brake setup with a much more robust system, offering increased stopping power and better heat management. It's important to note this kit excludes xDrive and M5 models, so be sure to check your specific vehicle's configuration.

At the heart of this kit are the 4-piston cast aluminum calipers, which are well-built and designed to provide consistent clamping force. Paired with these calipers are 345x28mm two-piece rotors. The rotors are drilled, which helps to dissipate heat and gasses, keeping the pads from overheating and losing effectiveness during hard braking. The two-piece design also helps reduce unsprung weight and allows for better thermal expansion compared to a single-piece rotor. The calipers come in a silver finish, giving your wheels a clean, performance-oriented look.

Installing a big brake kit like this is a substantial upgrade, and it's recommended to have it installed by a qualified technician. You'll want to ensure you have the correct brake fluid for the system and that it's bled properly after installation. This kit is a significant investment in your vehicle's performance and safety, offering a noticeable difference in braking feel and capability, especially under demanding conditions.
