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

This Brembo GT Big Brake Kit for the rear of your 2008-2013 BMW M3 (E90, E92, E93 chassis) includes everything you need to significantly upgrade your braking system. You'll get a pair of red 4-piston GT calipers, two-piece 345x28mm drilled rotors, and all the necessary hardware for installation. This kit is designed to provide a substantial improvement in stopping power and heat management, making it ideal for drivers who push their M3 hard on the track or demand consistent performance on the street.

The heart of this kit is Brembo's renowned GT caliper, a 4-piston forged aluminum unit known for its stiffness and consistent pedal feel. These calipers are paired with two-piece rotors, featuring a cast iron friction ring bolted to an aluminum hat. This design helps reduce unsprung weight and allows for better thermal management, as the aluminum hat can dissipate heat more effectively than a solid one-piece rotor. The drilled surface on the rotors helps to vent gases and heat away from the pad surface, which is especially beneficial during repeated hard braking events. The red caliper finish adds a distinct visual upgrade to your vehicle's wheel well.

Installing a big brake kit like this is a significant upgrade, and it's important to ensure you have the right tools and knowledge. While this kit is designed as a direct bolt-on replacement for the factory components, it's always recommended to consult the manufacturer's installation guide or seek professional assistance to ensure proper fitment and function. This kit is a popular choice for M3 owners looking for a noticeable increase in braking performance and durability, whether for spirited street driving or track day use.
