This is not some rare problem, hell my bearings where shot to shit at 31k when I went ahead and switched them out when I had a SC installed. Several were worn through the copper, at 31K!!!.
Been more than one engine blown at 6k, huge threads full of people with spun bearings blow engines super worn bearings when they changed them. In many cases it shows no symptoms before the engine goes as well, I promise you if all m3 owners cracked open their engine a great deal would show massive bearing wear.
As the cars get older and more miles are put on them you can expect to see even greater numbers of blown engines. If I would not of just went ahead and switched mine I would of lost my engine at 60k if not sooner and im just some random dude.
How many others are sitting on the same problem and are unaware??
Don't stick your head in the sand, its 2k for new upgraded rod bolts and WPC bearings installed to save a 20k engine. People spend that much on a useless front spoiler that will just get cracked.
