Brembo 06-12 325i (Excl. xDrive) Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type1-Black

If you're looking to significantly improve the stopping power and heat management for your 2006-2012 BMW 325i (excluding xDrive models), this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit replaces your factory rear brake components with a much larger and more robust setup, designed to handle repeated hard braking without fading.

At the heart of this kit are the 4-piston GT calipers, forged from cast aluminum for a strong yet lightweight housing. These calipers clamp down on substantial 345x28mm two-piece rotors. The rotors feature a slotted design, which helps to vent gases and dust away from the pad surface, maintaining consistent friction and preventing glazing. The two-piece construction allows the rotor and hat to expand and contract independently, reducing the risk of rotor warping under extreme heat. The black caliper finish adds a clean, performance-oriented look behind your wheels.

This kit is engineered to be a direct fit for the specified BMW 325i models, meaning it's designed to bolt on without requiring extensive modifications. While it's a substantial upgrade, it's important to ensure you have adequate wheel clearance for the larger calipers and rotors. This kit is a popular choice for drivers who push their vehicles hard, whether on the track or during spirited driving, and demand reliable, consistent braking performance.
