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

The 380x28mm, two-piece rotors in this Brembo GT Big Brake Kit are a key part of its improved stopping performance. This kit is specifically designed for the rear of 2019 and newer BMW 330i models, offering a substantial upgrade over the factory braking system. The larger rotor surface area and the robust four-piston calipers work together to handle heat more effectively and provide more consistent braking force, especially during spirited driving or repeated hard stops.

Brembo's GT Big Brake Kits are well-known for their track-inspired engineering, and this rear kit is no exception. The calipers are cast from aluminum for a good balance of strength and light weight, finished in a bright fluorescent yellow that stands out. The two-piece rotor design, featuring a cast iron friction ring and an aluminum hat, helps to reduce unsprung weight and allows for better thermal management by separating the heat-generating rotor from the hub assembly. The drilled rotor faces help to vent gases and heat away from the pad surface, contributing to a more stable pedal feel under demanding conditions.

When installing this kit, you'll be replacing your stock rear brake components with these high-performance parts. This upgrade is ideal for drivers looking to maximize their vehicle's braking capabilities, whether for track days, autocross, or simply for enhanced confidence on the street. Ensure you consult the manufacturer's installation guide for specific procedures and any required hardware not included in the kit.
