Brembo 00-03 M5/97-03 5-Series Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Drilled-Black

If you're looking to significantly improve the stopping power and heat management of your 2000-2003 BMW M5 or 1997-2003 5-Series, this Brembo GT Big Brake Kit for the rear is a solid choice. This kit replaces your factory rear brake components with larger, more capable hardware designed to handle increased thermal loads and provide more consistent braking performance, especially during spirited driving or track use.

At the heart of this kit are the Brembo 4-piston GT calipers, known for their robust construction and excellent thermal dissipation. These calipers grip a pair of 2-piece, 345x28mm rotors. The 2-piece design helps reduce unsprung weight and allows for better heat management compared to a single-piece rotor. The rotors themselves are drilled, which helps to vent gases and heat away from the pad surface, further improving performance and reducing fade. The calipers are cast aluminum for a good balance of strength and weight, and the rotors are finished in black to resist corrosion.

This kit is designed as a direct replacement for the rear axle, meaning it aims to install without requiring major modifications to your vehicle's existing brake system. It's important to note that while this kit is comprehensive, you should always refer to the manufacturer's installation instructions for specific details on mounting and brake bleeding procedures. Upgrading your rear brakes like this can make a notable difference in your vehicle's overall braking capability.
