Brembo 08-13 M3 Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-1-Black HA

If you're looking to significantly upgrade the braking performance on your 2008-2013 BMW M3, this Brembo GTS Big Brake Kit is a serious consideration. This kit replaces your factory rear braking components with a much more robust setup designed for demanding use, offering improved stopping power and heat management. It's built around a set of powerful 4-piston calipers and substantial 345x28mm two-piece rotors that can handle repeated hard braking without fading.

The calipers are cast aluminum, which keeps weight down while maintaining strength. They're paired with two-piece rotors featuring a slotted design. These slots help to sweep away dust and gas that can build up between the pad and rotor surface during aggressive driving, ensuring consistent contact and a more reliable bite. The rotors themselves are 345mm in diameter and 28mm thick, providing a larger surface area and greater thermal mass than stock, which is crucial for dissipating the intense heat generated during heavy braking. The black HA finish on the calipers adds a distinctive look to your M3's rear end.

This kit is designed as a direct replacement for the rear axle of the specified M3 models, meaning it aims to install without requiring extensive modifications. It includes everything you need to get these high-performance brakes installed, giving you the confidence to push your M3 harder on the track or during spirited driving. When you're investing in a big brake kit, you're looking for a noticeable difference in how your car stops, and this Brembo setup is engineered to deliver that.
