Brembo 08-13 M3 (E90/E92/E93) Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Black HA

This is the Brembo Rear GTS Big Brake Kit for your 2008-2013 BMW M3 (E90, E92, E93 chassis). It's designed to give your M3 a significant upgrade in stopping power and heat management, especially if you push your car hard on the track or during spirited driving. The kit includes everything you need to replace your stock rear braking system with a high-performance setup from a well-known name in braking technology.

At the heart of this kit are the 4-piston cast aluminum calipers, which offer a strong and rigid foundation for consistent braking force. These calipers clamp down on the included 345x28mm two-piece rotors. The rotors are drilled, which helps to dissipate heat and gasses, improving performance during repeated hard stops. The two-piece design allows the rotor and hat to expand and contract independently, reducing the risk of rotor warping under extreme thermal loads. The black HA finish on the calipers adds a clean, performance-oriented look to your rear wheels.

This kit is a comprehensive solution for M3 owners looking for a substantial improvement in braking performance. It's a direct replacement for your factory rear brake components, meaning no custom fabrication is needed for installation. You'll notice a more responsive pedal feel and greater confidence when braking from high speeds. Remember to consult the manufacturer's installation guide for specific details on mounting and any required break-in procedures to get the most out of this high-performance brake system.
