Brembo 09-16 Z4 sDrive 28i/30i/35i Front GT BBK 6 Piston Cast 380x32 2pc Rotor Drilled-Red

The 380x32mm, two-piece rotors in this Brembo GT Big Brake Kit are cast from a high-carbon iron alloy, a material chosen for its ability to handle the heat generated during aggressive braking. This kit is specifically designed for the 2009-2016 BMW Z4 sDrive models, including the 28i, 30i, and 35i variants, offering a significant upgrade over the factory braking system.

At the heart of this kit are the six-piston calipers, forged from aluminum for a strong yet lightweight housing that resists flex under heavy load. The calipers are paired with the two-piece rotors, which feature a drilled surface. Drilling helps to dissipate heat and remove brake dust and gas from the pad surface, promoting more consistent stopping power, especially during repeated hard braking. The two-piece design allows the rotor and hat to expand and contract independently, reducing the risk of rotor warping and improving thermal management.

This Brembo GT Big Brake Kit includes everything needed for installation, such as the calipers, rotors, brake lines, and mounting hardware. Upgrading to a big brake kit like this can dramatically improve your vehicle's stopping performance, reduce brake fade during spirited driving or track use, and provide a more confident feel at the pedal. It's a substantial improvement for drivers who push their Z4's limits.
