The Brembo GT front big brake kit for 2020+ X3M and 2020+ X4M applications upgrades the front brakes with 8-piston cast calipers and 412x38 mm two-piece slotted Type‑1 rotors to boost stopping power and thermal management. Slotted rotor faces improve pad bite and clear debris for consistent braking under spirited driving, while the white calipers offer a clean visual complement to the vehicle’s performance character.
