I just changed mine.

I read that you have to just make them tight because you can't get a torque wrench in there. That's a severe understatement for a 210. Getting them out was no problem using the air impact wrench, but putting them back in was a real pain, especially in the front. I could hardly get a wrench to stay on the nuts when tightening. I think they're tight enough.

Changing them both took about an hour, plus another two hours to torque the front six bolts. It would have been a lot easier had I removed the transmission mount, but I didn't want to loosen the exhaust. If there's a next time, I will.

If I get a chance, I'll post pictures of the old disks. They're not as bad as any posted here, but I don't know if they've ever been changed.
