The Brembo GT front big brake kit for 2012–2018 G63 and G65 AMG models replaces the front hardware with 8-piston cast calipers and 412x38 mm two-piece drilled rotors to improve braking capacity and heat management. The drilled rotors aid cooling and water dispersion while the red calipers provide visual distinction; the kit is specified as a complete front upgrade for those AMG applications.
