The Brembo GT big brake kit for 2001–2006 M3 (E46) front applications is a six‑piston cast front system with 380×32mm two‑piece drilled rotors in yellow. Built to replace factory hardware with larger calipers and two‑piece rotors, the kit increases rotor area and airflow through drilled faces to help control temperatures under sustained braking while offering a bold aesthetic.
