The Brembo GT big brake kit for 2011–2016 BMW 528i and 528i xDrive is a front 6‑piston system with two‑piece cast 405×34 mm rotors, drilled finish and silver calipers. This front upgrade swaps in larger multi‑piston calipers and two‑piece rotors to improve braking consistency and help control heat; drilled rotor faces enhance cooling and aid in shedding water and pad material.
