Ive tried just about all brands of rotors on my benzes. I will share my opinion. First off, Ive had good luck with Ate, Ate premium one, and Balo. I would buy one of those. I have a full set of premium one's on the 95 E320. It has been driven through a nasty ny winter and havent rusted at all. The car even sits for periods of time. However, there is a tradeoff. They are a little noisier than the rest (due to the slotting). And by noise, i dont mean squeeking. Im talking about a low tone, almost grinding like noise. I guess it could be compared to tires with huge knobby's on them. Btw, the car has brand new michelins on it. As for performance, its definetely over kill on a daily driver. None the less, excellent quality. And I am knitpicking about the noises. Its not as bad or as loud as you would think.

Ate (regular) and Balo are also good quality and are pretty much OEM (ATE is OEM isnt it?). You wont get the noises that the premium ones make.

My greatest advice to you: Dont skimp on the brake pads. Buy OEM, Textar, or Pagids. I would not buy any other. Use a good anti-seize compound, coat the backs of the pads. Get a cordless drill with a wire brush on it, clean up the hub before putting the new rotor on, coat that with anti-seize too. Also, you could clean the inside rim mounting surface as well. Put some anti-seize on that too! Best of luck. A very simple job indeed.
