I am contemplating joining the ranks of X5M owners and looking at a 2011 with about 60K miles. Pre inspection by this out of town dealer yielded the following rotor thickness but dealer doesn't know if they are close to minimum tolerances. I can't find anything online or this forum for X5M rotors. My local BMW dealers is non-responsive. So I'm turning to this community for help. Does anyone know what the minimum thickness is? Here are the current measurements.

RF 34.80mm, LF 34.80mm
RR 23.32mm, LR 23.53mm

At $450 per rotor that would be a pricey replacement. Prior service history did not list rotor replacement so I am assuming these are the original rotors. Pads are at about 50%. I'll bet this is the second set of pads on original rotors.

Thanks for your help.
