The Brembo Big Brake Kit for 2015–2018 M3 models (excluding carbon‑ceramic brakes) rear applications offers a rear GTS BBK built with four‑piston cast calipers and 345x28 two‑piece rotors. This drilled-rotor black finish kit is specified for M3 rear fitments that do not use carbon‑ceramic systems, and it replaces the stock rear hardware with a more substantial braking package.
