The Brembo big brake kit for 2015–2018 BMW M3 models equipped with carbon-ceramic brakes includes six-piston billet calipers and 405×34 mm two-piece nickel-plated rotors with drilled faces. This direct-fit front package is aimed at improving thermal control and consistent stopping under track or heavy street use; drilled rotors help evacuate gases and water while the two-piece construction supports maintenance.
