Brembo 08-13 M3 Rear GTR BBK 4 Piston Billet 380x28 2pc Rotor Slotted Type1 - Nickel

This is the Brembo Rear GTR Big Brake Kit for the 2008-2013 BMW M3. It's a comprehensive upgrade designed to significantly improve your M3's braking performance, especially under demanding conditions. The kit includes four-piston billet aluminum calipers, two-piece 380x28mm slotted rotors, and all the necessary hardware for installation.

Brembo is known for its high-performance braking systems, and this GTR kit is a prime example. The calipers are forged from billet aluminum, which is both strong and lightweight, helping to reduce unsprung mass. The four-piston design offers increased clamping force and better pad wear distribution compared to smaller calipers. The two-piece rotors feature a 380mm diameter and 28mm thickness, providing a larger surface area for heat dissipation and improved stopping power. The Type 1 slotting pattern on the rotors helps to sweep away dust and gas, maintaining consistent braking performance even during repeated hard stops. The nickel finish on the rotors adds a layer of corrosion resistance and a distinct look.

This kit is a substantial investment for the serious M3 owner looking for track-ready braking. It's designed as a direct replacement for the factory braking system, though professional installation is recommended due to the complexity of big brake kits. Ensure you have adequate wheel clearance for the larger calipers and rotors before purchasing. This kit represents a significant step up in braking capability, offering improved fade resistance and pedal feel for spirited driving and track use.
