The Brembo GT front big brake kit for 2009–2012 Mercedes-Benz SL550 (R230) applications provides six-piston calipers and two-piece 355×32 mm cast rotors, slotted Type 3 in yellow. As a direct front upgrade, it increases rotor size and adds multi-piston calipers for improved braking control, while the two-piece rotor design allows easier servicing and replacement of wear items.
