Brembo 12-14 328i Excl xDrive/MSport Brakes Rr GT BBK 4Pis Cast 345x28 2pc Rtr Slot Type3-Red

This Brembo GT Big Brake Kit for the rear of your 2012-2014 BMW 328i (excluding xDrive and M Sport models) includes everything you need to significantly upgrade your braking performance. You'll get a pair of red 4-piston cast aluminum calipers, two 345x28mm two-piece slotted rotors, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear brake setup with a much more robust system, offering improved stopping power and heat management.

The calipers are constructed from cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the 4 pistons. These pistons work together to apply even pressure across the brake pads, leading to more consistent and powerful braking. The rotors are a two-piece design, meaning the hat and the friction surface are separate. This design helps reduce heat transfer to the hub and allows for more precise rotor runout. The 345x28mm size offers a larger swept area compared to stock, further enhancing braking capability. The Type 3 slots on the rotor surface are designed to help vent gases and dust away from the pad surface, maintaining optimal friction even under heavy use.

Upgrading to a big brake kit like this is a substantial change that can make a noticeable difference, especially if you push your car hard or plan on track use. It's important to note that while this kit is designed as a direct replacement for the specified models, it's always a good idea to consult the manufacturer's installation guide for any specific tool requirements or procedures. Proper bedding-in of the new pads and rotors is also crucial to achieve the best performance from this Brembo kit.
