Brembo 19+ 330i Front GT BBK 6 Piston Cast 380x34 2pc Rotor Slotted Type3-White

The 380x34mm two-piece rotors in this Brembo GT Big Brake Kit are cast iron, a material chosen for its excellent thermal properties and durability under heavy braking. This kit is specifically designed for the 2019 and newer BMW 330i, offering a significant upgrade over the factory braking system. The six-piston calipers are a key component, providing increased clamping force and better heat dissipation, which translates to more consistent stopping power, especially during repeated hard stops or track use.

This kit features slotted rotors, which help to sweep away dust and gas that can build up between the pad and rotor surface. This slotting pattern helps maintain a clean contact patch, ensuring optimal friction and preventing brake fade. The calipers themselves are a cast aluminum construction, balancing strength with a reduction in unsprung weight. The two-piece rotor design allows for better thermal management, as the aluminum hat can dissipate heat independently from the iron braking surface, reducing the risk of rotor warping.

Installing a big brake kit like this is a substantial modification that can change the feel and performance of your vehicle's braking. It's important to ensure all components are installed correctly according to the manufacturer's instructions. This kit is a comprehensive solution for drivers looking to significantly enhance their vehicle's braking performance and reliability.
