Brembo 11-12 1M Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-3-Black HA

This is the Brembo Rear GTS Big Brake Kit for the 2011 and 2012 BMW 1M. It's a comprehensive upgrade designed to significantly improve your braking performance, especially under demanding conditions. The kit includes a pair of four-piston calipers, two-piece 345x28mm slotted rotors, and all the necessary hardware to get them installed. If you're looking to enhance stopping power and heat management for your 1M, this Brembo kit is a serious consideration.

The calipers are cast aluminum, which keeps weight down while maintaining strength. They feature a four-piston design, meaning more clamping force is applied to the rotor surface evenly. This translates to better pedal feel and more consistent braking. The rotors are a two-piece design, with a 345mm diameter and 28mm thickness, offering a large surface area for heat dissipation. They are Type-3 slotted, which helps to vent gases and debris away from the pad surface, maintaining optimal friction and preventing fade during hard use. The black finish on the calipers adds a clean, performance-oriented look to your wheels.

This kit is a direct replacement for the factory rear brake components, simplifying the installation process. It's designed to work with your existing master cylinder and brake lines, though upgrading those can further enhance performance. When installing a big brake kit like this, it's always a good idea to have fresh brake fluid on hand and consider bleeding the entire system to ensure optimal performance. This Brembo kit represents a substantial investment in your vehicle's braking system, offering a noticeable improvement in both performance and durability.
