Brembo 11-12 1M Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type-1-Red

If you're looking to significantly upgrade the braking performance on your 2011-2012 BMW 1M, this Brembo GT Big Brake Kit is a serious consideration. This kit focuses on the rear axle, providing the stopping power and heat management needed for spirited driving and track use. It replaces your factory rear brake components with a robust, high-performance setup designed to handle demanding conditions.

At the heart of this kit are the Brembo 4-piston calipers, known for their solid construction and consistent clamping force. These calipers work with large 380x28mm two-piece rotors. The two-piece design helps manage heat and reduce unsprung weight compared to a single-piece rotor. The rotors themselves are slotted, which helps to clear out brake dust and gases that can build up between the pad and rotor surface, ensuring a cleaner contact patch and more reliable braking, especially under heavy use. The calipers come finished in a distinctive red, adding a visual upgrade to your vehicle's appearance.

This kit includes everything needed for the rear brake upgrade, ensuring a comprehensive solution. When installing a big brake kit like this, it's always recommended to consult the manufacturer's installation guide for specific procedures and torque specifications. Upgrading your rear brakes in conjunction with your front brakes will provide the most balanced and effective braking system for your 1M.
