Here is a pic of my rotor (its off a C43 but I believe the C43 and E55 used the same brakes, it has a 210 part number)
It says 30.4mm on the rotor hat (crappy iphone pic)
Here is a screen shot from the WIS that states the limit was reduced from 30.4mm to 29.4

Just did my brakes and saw this mark. It should be mentioned that this mark is not useful if you do not turn your discs. No pads wear down the outer edge which means if you do if you just replace pads (which is typical), the wear indicators are never reached but the disc itself is as thin as it is. It must be measured
