Brembo 19+ 330i Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type3-Silver

Brembo is well-known for making high-performance braking components, and this Rear GT Big Brake Kit (BBK) continues that tradition. If you're looking to significantly upgrade the stopping power and heat management on your 2019 and newer BMW 330i, this kit is designed to do just that. It replaces your factory rear brakes with a much more robust system, built to handle more demanding driving conditions and provide a more confident pedal feel.

This kit features a set of four-piston calipers, which offer more clamping force than stock, paired with substantial 380x28mm two-piece rotors. The two-piece design helps manage heat more effectively by allowing the rotor and hat to expand independently, reducing the risk of warping. These rotors are slotted with Brembo's Type 3 pattern, which helps to vent gases and dust away from the pad surface, maintaining consistent braking performance even under heavy use. The cast caliper construction is solid and built to withstand the rigors of spirited driving.

When installing a kit like this, you're looking at a significant upgrade over your original equipment. The larger rotors and calipers require proper bedding-in procedures to ensure optimal performance and longevity. This kit is a comprehensive solution for the rear of your 330i, aiming to provide improved fade resistance and a more direct response from your brake pedal.
