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

This is the Brembo Rear GTS Big Brake Kit for 2019 and newer BMW 330i models. 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 380x28mm rotors that are drilled for heat dissipation, and all the necessary hardware to get them installed. If you're looking to get the most out of your 330i on the track or during spirited driving, this kit offers a substantial step up from the factory setup.

The calipers are cast aluminum, which keeps them strong yet relatively lightweight. They feature a four-piston design, meaning more pad surface area contacts the rotor, leading to better clamping force and more consistent braking. The two-piece rotors are a notable feature; the 380mm diameter provides a large braking surface, and the 28mm thickness offers excellent thermal mass to handle heat. The drilled pattern on the rotors helps vent gases and heat away from the braking surface, which is crucial for preventing fade during repeated hard stops. This kit is engineered to be a direct fit for the specified 330i models, simplifying the installation process compared to custom setups.

When installing a big brake kit like this, it's important to ensure your entire braking system is in good working order. While this kit replaces the primary braking components, you might also want to consider high-performance brake fluid to match the increased capability of the calipers and rotors. This Brembo kit is a well-built solution for drivers who demand more from their vehicle's stopping power.
