The Brembo GTS front big brake kit for 2015–2018 BMW M3 (excludes CC variant) combines six-piston cast calipers with 365x34 two-piece cast rotors featuring slotted Type 1 faces in black with HA treatment. This direct-replacement front BBK brings larger calipers and two-piece rotors to the M3 platform for improved thermal handling and more consistent stopping on both road and track.
