Brembo 11-12 1M Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-1-Silver

This Brembo GT Big Brake Kit for the 2011-2012 BMW 1M includes everything you need to significantly upgrade your rear braking performance. You get a pair of Brembo's well-known 4-piston GT calipers, a set of 345x28mm two-piece rotors with a slotted surface, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear brake components with a much more robust setup, offering improved stopping power and heat management for spirited driving or track use.

The calipers are cast from a strong aluminum alloy, housing four pistons that apply even pressure across the brake pad surface. This design helps to dissipate heat more effectively than smaller, single-piston calipers. The two-piece rotors feature a cast iron friction ring attached to an aluminum hat, which helps reduce unsprung weight and further aids in heat management by allowing the rotor to expand and contract more freely. The slotted rotor surface is a key feature for performance driving, as it helps to sweep away brake dust and gases that can build up between the pad and rotor, maintaining consistent braking performance even under heavy load. The silver finish on the calipers offers a clean, performance-oriented look behind your wheels.

When installing a big brake kit like this, it's important to ensure you have the correct tools and follow the manufacturer's instructions carefully. While this kit is designed as a direct replacement for the factory brake system, proper installation is crucial for optimal performance and safety. You may also want to consider upgrading your brake fluid to a higher temperature rating to take full advantage of the kit's capabilities.
