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

This Brembo Rear GTS Big Brake Kit includes everything you need to upgrade your 2011-2012 BMW 1M's braking system. You get a pair of 4-piston cast iron calipers, two 345x28mm two-piece rotors that are drilled for heat dissipation, and all the necessary hardware to get them installed. This kit is designed to give your 1M a significant improvement in stopping power and heat management, which is crucial for spirited driving or track use.

The calipers are a robust 4-piston design, meaning they apply more even pressure across the brake pad surface for better contact and fade resistance. The two-piece rotor construction is notable because it allows the rotor ring to expand and contract independently of the hat, reducing the risk of rotor warping under extreme heat. The drilled holes on the rotor surface help to vent gases and heat away from the pad, keeping your brakes cooler and performing more consistently when you need them most. Brembo is well-known for its high-performance braking components, and this kit reflects that reputation with its solid build and thoughtful design.

When installing a big brake kit like this, it's always a good idea to have a fresh set of high-performance brake fluid on hand, as bleeding the system is a required step. You'll also want to ensure your brake lines are in good condition, as they are a critical part of the hydraulic system. This kit is a substantial upgrade for the serious enthusiast looking to maximize their vehicle's braking capabilities.
