Brembo 06-12 325i/328i (Excl. xDrive) Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Drilled-Black

Brembo is well-known for their high-performance braking systems, and this Rear GT Big Brake Kit (BBK) is a prime example of their expertise. Designed for the 2006-2012 BMW 325i and 328i models, excluding xDrive variants, this kit is built to significantly improve your vehicle's stopping power and heat management.

This kit features robust 4-piston cast aluminum calipers, which offer a strong and consistent clamping force on the rotors. The calipers work with 2-piece, 345x28mm rotors that are drilled for improved heat dissipation. The 2-piece design allows for better thermal management and can reduce unsprung weight compared to a single-piece rotor. The drilled surface helps to vent gases and moisture, which can improve braking performance, especially during repeated hard stops. This kit is designed to be a direct replacement for your factory rear braking system, though professional installation is recommended due to the complexity of big brake kits.

When you're looking to upgrade your BMW's braking capabilities, especially for spirited driving or track use, a big brake kit like this Brembo offering makes a substantial difference. It's a comprehensive solution that addresses both the hardware and the performance needs of a demanding braking system. Ensure you consult the manufacturer's installation guide for specific details regarding hardware and setup.
