Brembo 12-14 328i Excl xDrive/MSport Brakes Rr GT BBK 4Pis Cast 345x28 2pc Rtr Slot Type1-Silver

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 get a pair of Brembo 4-piston calipers, two 345x28mm two-piece slotted rotors, and all the necessary hardware for installation. This kit is designed to replace your factory rear brake setup with a more robust and capable system, offering improved stopping power and heat management.

The calipers are cast from high-grade aluminum for a strong yet lightweight housing, finished in a sleek silver. They feature a 4-piston design, which increases the pad surface area contacting the rotor and distributes clamping force more evenly. This translates to more consistent braking, especially under heavy use. The rotors are a two-piece design, meaning the hat and rotor ring are separate components. This design helps reduce weight and allows for thermal expansion without inducing rotor stress, which can lead to warping. The 345x28mm size offers a larger swept area compared to stock, further enhancing braking capability. The Type 1 slotting pattern on the rotor faces helps to vent gases and dust away from the pad surface, maintaining optimal friction and reducing fade during spirited driving or track use.

Installing a big brake kit like this is a significant upgrade for drivers who push their vehicles hard or want the best possible stopping performance. While this kit is designed as a direct replacement for the factory rear brake components on the specified 328i models, it's always recommended to consult the manufacturer's installation guide for specific details and torque specifications. This kit represents a substantial improvement in both the thermal capacity and the overall stopping force of your vehicle's braking system.
