Brembo 19+ 330i Rear GTR BBK 4 Piston Billet 380x28 2pc Rotor Drilled-Nickel

The 380x28mm two-piece rotor design in this Brembo GTR Big Brake Kit is a key indicator of its performance focus. This kit is built for the rear of 2019 and newer BMW 330i models, aiming to provide a substantial upgrade over the factory braking system. It features a robust 4-piston billet caliper, designed to handle the increased demands of spirited driving and track use.

This kit includes everything needed to install the GTR calipers and the nickel-plated, drilled two-piece rotors. The billet aluminum construction of the calipers offers a strong yet lightweight foundation, while the drilled rotor design helps dissipate heat and expel gases and moisture, maintaining consistent braking performance even under heavy load. The nickel plating on the rotors adds a layer of corrosion resistance, important for longevity and appearance.

Installing a Big Brake Kit like this is a significant modification that can change the feel and capability of your vehicle's braking. It's designed for drivers who push their cars hard and require a braking system that can keep up. Ensure you consult the manufacturer's installation guide for specific details and any additional components that may be recommended for optimal performance and safety.
