The Brembo GT front big-brake kit for 2017–2023 530i and 530i xDrive applications replaces the factory front braking with six-piston cast calipers and two-piece 380×34 mm rotors in a Type 1 slotted pattern, finished in yellow. The slotted rotors improve pad sweeping and heat management, providing a tangible stopping upgrade for the listed BMW variants without changing front geometry.
