Brembo 19+ 330i Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type1-Red

This is the Brembo GT Big Brake Kit for the rear of your 2019 and newer BMW 330i. It's a comprehensive upgrade designed to significantly improve your car's braking performance, especially under demanding conditions. The kit includes a pair of four-piston calipers, two-piece slotted rotors measuring 380x28mm, and all the necessary hardware to get them installed. Brembo is well-known for its high-performance braking systems, and this kit represents their GT line, which is built for serious drivers who want the best stopping power.

The calipers are cast aluminum, which keeps them strong yet relatively lightweight, and they feature a four-piston design. This means more clamping force is applied to the rotor surface evenly, leading to better braking feel and more consistent stopping power. The rotors are a two-piece design, with a 380mm diameter and 28mm thickness, and they are slotted. These slots help to vent gases and heat away from the pad surface, which is crucial for preventing brake fade during repeated hard stops. The Type 1 slotting pattern is chosen for its balance of performance and noise reduction. This kit is a substantial upgrade over the factory braking system, offering improved heat dissipation and a more direct pedal feel.

When installing a big brake kit like this, it's important to ensure you have the right tools and follow the manufacturer's instructions carefully. While this kit is designed to fit the specified vehicles, it's always a good idea to double-check clearances, especially if you have modified your suspension or are running non-standard wheels. This kit is a significant investment in your vehicle's performance and safety, providing a noticeable difference in how your car stops, particularly during spirited driving or track use.
