Brembo 06-12 325xi/328xi Front GT BBK 4 Piston Cast 365x29 2pc Rotor Drilled-Black

If you're looking to significantly improve your BMW 325xi or 328xi's braking performance, especially for track days or aggressive street driving, this Brembo GT Big Brake Kit is a serious upgrade. This kit replaces your factory front brakes with a much larger and more capable system designed to handle higher temperatures and provide more consistent stopping power. It’s a comprehensive package that addresses the limitations of stock brakes when pushed hard.

At the heart of this kit are the 4-piston cast aluminum calipers, which offer increased clamping force over the factory setup. These calipers work with substantial 365x29mm two-piece rotors. The two-piece design allows the rotor and hat to expand and contract independently, which helps reduce stress and prevent warping under extreme heat. The rotors themselves are drilled, a feature that helps dissipate heat and gases, keeping the pads cooler and providing a more reliable bite. The black finish on the calipers adds a clean, performance-oriented look to your front end.

This Brembo GT BBK is designed as a complete front brake system replacement. It includes everything you need to upgrade your front brakes, from the calipers and rotors to the necessary mounting hardware and brake lines. While this is a bolt-on kit, it's a substantial modification that will change the feel and performance of your car's braking. For installation, it's recommended to consult the manufacturer's instructions, as specific tools and procedures may be required to ensure proper fitment and function.
