The Brembo big brake kit for BMW M3 (2015–2018) specified for cars with carbon‑ceramic brakes upgrades the rear with four‑piston cast calipers and two‑piece 380×28 mm rotors. This GT kit uses slotted Type‑3 rotors in a yellow finish to improve heat dissipation and maintain consistent pedal feel under heavy braking on CC‑equipped M3 rear applications.
