GIRODISC A2-030DS Rear Brake Rotor Kit for MERCEDES-BENZ SL63 AMG (R230) / SL55 AMG (R230)

GiroDisc 2-piece brake rotors are a direct replacement for your factory rotors, requiring no modifications. The rotor attaches directly to the vehicle and works perfectly with the original calipers. Once the Girodisc system is installed, simply replace the cast iron rotor ring when needed. The two-piece brake rotors are approximately 2 kg lighter than stock rotors. This reduction in rotational and unsprung mass provides quicker acceleration and suspension response.
