When I replaced my first set of front rotors, the ones I took off were painted! I bought replacements at the dealer; they were not. I believe Zimmerman is OEM. Last time around I got a set at The Benz Bin, and shot a few light coats of black paint on them. Eastwood Chassis Black. So far the paint is holding up well. That's the only way you're going to get painted rotors if that's what you want. The stock wheels are open enough to make the difference visible, even if it does turn a simple brake job into a three hour job!

Be sure to paint the calipers before you take the old rotors off; makes it look much nicer.
