The Brembo rear GTS big brake kit for 2003–2009 E55 AMG pairs four-piston calipers with 380×28 mm two-piece drilled rotors finished in black. Cast components and two-piece rotor construction support heat dispersion, while the drilled face aids gas and water evacuation for more consistent pedal feel. This rear kit offers a substantial braking upgrade for compatible E55 AMG applications.
