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

If you're looking to significantly upgrade the braking performance of your 2011-2012 BMW 1M, this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit is designed to provide a substantial improvement in stopping power, heat management, and overall feel, especially during demanding driving conditions where stock brakes might start to fade. It's a comprehensive package built around Brembo's expertise in high-performance braking systems.

At the heart of this kit are the 4-piston calipers, forged from aluminum for a strong yet lightweight construction, finished in a classic silver. These calipers clamp down on large 345x28mm two-piece rotors. The rotors themselves are drilled, which helps to dissipate heat and gas away from the pad surface, maintaining consistent braking performance. The two-piece design also helps reduce unsprung weight and allows for better thermal management compared to a single-piece rotor. Brembo is well-known for its robust manufacturing processes, and this kit reflects that commitment to producing well-built braking components that can handle the rigors of spirited driving and track use.

This kit includes everything you need to install the rear big brake system, including the calipers, rotors, mounting brackets, and high-performance brake pads specifically chosen to work with this setup. While installation is a significant undertaking, it's designed to be a direct bolt-on for the specified vehicle, meaning no modifications to the suspension or chassis are typically required. However, it's always recommended to consult the manufacturer's installation guide for detailed instructions and torque specifications. Upgrading to a big brake kit like this can fundamentally change how your car feels and performs under braking, offering greater confidence and control.
