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

This Brembo GT Big Brake Kit for the rear of your 2019 and newer BMW 330i includes everything you need to significantly upgrade your braking performance. You'll get a pair of Brembo's 4-piston GT calipers, two 380x28mm two-piece brake rotors that are drilled for heat dissipation, and all the necessary hardware to complete the installation. This kit is designed to give your 330i a substantial improvement in stopping power and feel, especially under demanding driving conditions.

The calipers in this kit are cast aluminum, which keeps them strong yet relatively lightweight. They house four pistons each, allowing for more even pressure distribution across the brake pad surface. This translates to more consistent braking force and better control. The two-piece rotors are a notable feature; the 380mm diameter provides a larger braking surface, while the 28mm thickness offers increased thermal mass to handle heat buildup. The drilled pattern on the rotors helps to vent gases and heat away from the pad surface, which is crucial for maintaining performance during repeated hard stops. This design helps prevent brake fade and keeps your braking consistent when you need it most.

Installing a big brake kit like this is a significant upgrade for your vehicle's performance. While it's a direct fit for the specified 330i models, it's always a good idea to consult the manufacturer's installation guide for specific torque values and procedures. This kit is a popular choice for drivers looking to enhance their car's track performance or simply gain more confidence in their street driving, especially if they frequently encounter situations requiring strong, reliable braking.
