Brembo 12-14 328i MSport Brakes Excl xDrive Rr GT BBK 4Pis Cast 345x28 2pc Rotor Drilled-Silver

This Brembo GT Big Brake Kit for the rear of your 2012-2014 BMW 328i MSport (excluding xDrive models) includes everything you need to significantly upgrade your braking performance. You get a pair of cast aluminum 4-piston calipers, two-piece 345x28mm drilled rotors, and all the necessary hardware for installation. This kit is designed to replace your stock rear brake components with a much more robust setup, offering a substantial improvement in stopping capability, especially under demanding conditions.

The calipers are crafted from cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the 4-piston design. This piston configuration allows for more even pad pressure distribution across the rotor surface, leading to more consistent braking and better heat management. The two-piece rotors feature a 345mm diameter and 28mm thickness, providing a larger surface area for the pads to grip and dissipate heat. The drilled pattern on the rotors helps to vent gases and heat away from the braking surface, further enhancing performance and reducing the risk of fade during hard braking. This combination of larger, well-designed components makes a noticeable difference when you need to slow down quickly and confidently.

Installing a big brake kit like this is a significant upgrade for your vehicle's performance. It's recommended to consult the manufacturer's installation guide for specific instructions, as proper setup is crucial for optimal performance and safety. While this kit focuses on the rear brakes, it's designed to work harmoniously with your existing front braking system, providing a balanced and improved overall braking experience for your 328i.
