Brembo 19+ 330i Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Drilled-Yellow

This Brembo GT Big Brake Kit for the rear of your 2019 and newer 330i includes everything you need to significantly upgrade your braking system. You get a pair of 4-piston calipers, two 380x28mm two-piece rotors (drilled), caliper mounting brackets, and all the necessary hardware to get them installed. This kit is designed to provide a substantial improvement in stopping power and heat management, making it a solid choice for drivers looking to push their vehicles harder or simply want the best braking performance available.

The heart of this kit is Brembo's renowned GT caliper, cast from aluminum for a strong yet lightweight design. Its 4-piston configuration allows for more even pad pressure across the rotor surface, leading to better braking feel and more consistent performance, especially under heavy use. The two-piece rotors are a key component for heat dissipation; the cast iron braking surface is separate from the aluminum hat, allowing them to expand and contract independently without causing rotor warp. The drilled pattern on the rotors helps to vent gases and heat away from the pad surface, further enhancing performance and preventing fade during spirited driving or track use. The calipers come in a striking yellow finish, adding a visual upgrade to match the performance gains.

Upgrading to a big brake kit like this is a significant modification that can change the feel and capability of your vehicle. It's important to ensure you have adequate cooling for your brakes if you plan on frequent track use, and always refer to the manufacturer's installation guide for proper fitment and torque specifications. This kit represents a top-tier braking solution, offering a blend of advanced materials, robust construction, and race-proven technology.
