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

Brembo is a name synonymous with high-performance braking systems, and their GT Big Brake Kits are a testament to that reputation. If you're looking to significantly upgrade the stopping power and feel of your 2006-2012 BMW 325i or 328i (excluding xDrive models), this rear GT BBK is a serious consideration. This kit is designed to replace your factory rear brake components with a much more robust setup, offering improved thermal management and consistent performance, especially during spirited driving or track use.

At the heart of this kit are the 4-piston cast aluminum calipers, finished in a striking yellow, paired with a 2-piece rotor design. The rotors measure 345x28mm and feature a drilled surface pattern, which helps to dissipate heat and gasses more effectively than solid rotors, leading to more reliable braking under heavy load. The 2-piece rotor construction allows for greater thermal expansion and can reduce unsprung weight compared to a single-piece rotor. This advanced setup works together to provide a firmer pedal feel and more predictable deceleration, giving you greater confidence behind the wheel.

When installing a big brake kit like this, it's important to ensure you have the correct tools and refer to the manufacturer's installation instructions. While this kit is designed for a direct fit on the specified BMW models, it's always wise to confirm compatibility with your specific vehicle's wheel size, as the larger calipers and rotors may require a minimum wheel diameter. This Brembo GT BBK is a substantial upgrade for those who demand more from their vehicle's braking system.
