Hi, all. I replaced the front rotors on my '12 S63 with OEM parts a year or so ago, which obviously took a big chunk out of my wallet. (Pads were TRW.) My rear rotors and pads were at their life's end at 81k miles, so I bought a pair of BrakeBest rotors (dimpled just like factory) from O'Reilly for $86 each and Duralast ceramic pads from AutoZone for $32. All in for less than $200, which is certainly better than the $3,200 my indy shop quoted me using all OEM parts. I installed them in my garage yesterday in about two hours, and everything fit perfectly. The only trouble I had was getting the old rotors off, which were basically cemented to the hubs. Beating them with a BFH freed them after about 15 minutes. So, just wanted to let you guys know that you don't have to pay an arm and a leg for the rear parts.
