Less than 1%, IF its not taken to the track. On the track the M97 bearings have the highest failure rates, by far.

When Porsche added bearing diameter, and increased surface speed of the bearing, that was great for lower RPM street service, but horrible for sustained high speed operation. I have a directive about this, if you email us.
