It's funny you ask, but I got the brakes as a gift from RENNTech because my father is a mercedes dealer so I don't know exactly how much. I do know that the rotors they sent me were worn, and my dad bought new ones which he said costed him an arm and a leg, but i would estimate maybe around $2,000 for the whole set.???? I know the calipers are actually made by brembo because it is imprinted on the back, so they are good, and i believe the front rotors are close to 13'' and the rears are close to 12''. Ill try and find out the pricing and post it for you
