Brembo 01-06 M3 Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Slotted Type-3-Black

If you're looking to significantly improve the stopping power and heat management on your 2001-2006 BMW M3, this Brembo GT Big Brake Kit for the rear is a serious upgrade. This kit is designed to handle the demands of spirited driving and track use, offering a substantial improvement over the factory braking system. It's built around robust 4-piston calipers and large 345x28mm two-piece rotors, engineered to dissipate heat effectively and provide consistent braking performance when you need it most.

The calipers in this kit are cast aluminum, which keeps them strong yet relatively lightweight. They house four pistons, providing more clamping force than typical two-piston calipers, which translates to better brake pedal feel and shorter stopping distances. The rotors are a two-piece design, meaning the hat and the friction surface are separate. This design allows for better thermal management as the two pieces can expand and contract independently, reducing the risk of rotor warping. The Type-3 slotting pattern on the rotors is a notable feature; these slots help to sweep away brake dust and gases that can build up between the pad and rotor surface, maintaining optimal friction and preventing fade during hard braking. The black finish on the calipers adds a clean, performance-oriented look to your M3.

This kit includes everything needed to get your M3's rear brakes upgraded to a high-performance level. You'll find the calipers, the two-piece slotted rotors, brake lines, and all the necessary hardware for installation. While this is a bolt-on kit, it's a complex job that requires careful attention to detail. It's recommended to have a qualified mechanic perform the installation to ensure everything is set up correctly for optimal performance and safety. This Brembo GT BBK is a substantial investment in your M3's performance, offering a significant boost in braking capability for both street and track driving.
