Considering swapping the REAR brakes from my 02 W210 E55 with the rears from a CL55 ( AMG 4 Pots calipers ) . Has anyone done that ? I know the rotors/ calipers etc are different, but what is involved in swapping? Custom Bracket for the caliper? I know the rotors are the same thickness between the two cars but they are the same thickness at 28mm....I also know that the AMG Calipers are Brembos, are they same as the Brembo calipers offered by the GT Kits ? Meaning the same weight or the AMG are heavier? Any guidance or help from the experts will be greatly appreciated.
