should fit as well which is the (drilled) rotor for the SL55/65...
the rear calipers should be here before the weekend. still have not ordered the rotors and pads yet. called the dealer parts dept but they couldn't tell me any description about the two rotors. i know the part number only differ by one number but it's kind of strange that the rotor for AMG SL 55/65 has the same size as the regular SL550. does anyone know for sure? i want drilled rotors to match the front but i hate to pay $200 and can't return it. does anyone know a store for rotors where you can return it if they don't fit? pepboys?
