Brembo 06-12 325i/328i (Excl. xDrive) Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Red

Brembo is well-known for their high-performance braking systems, often found on European sports cars right from the factory. This Rear GT Big Brake Kit (BBK) is designed to bring that same level of stopping power and control to your 2006-2012 BMW 325i or 328i, excluding xDrive models. If you're looking to significantly improve your car's braking performance, especially for spirited driving or track use, this kit is a substantial upgrade over the stock setup.

This kit features robust 4-piston cast aluminum calipers, which offer increased clamping force and better heat dissipation compared to smaller, single-piston calipers. The calipers work with a 2-piece rotor design, measuring 345x28mm. The 2-piece construction allows the rotor to expand and contract more freely with temperature changes, reducing the risk of warping. These rotors are drilled, which helps to shed heat and gasses, maintaining consistent braking performance even under heavy use. The kit includes everything needed for installation, ensuring a direct fit for the specified BMW models.

Upgrading to a big brake kit like this Brembo system is a significant modification that can change the feel and capability of your vehicle's braking. It's a popular choice for those who demand more from their car's stopping power, whether for track days, autocross, or simply for enhanced confidence on the street. Ensure you consult the manufacturer's installation guide for specific details regarding fitment and any other components that may be recommended for optimal performance.
