Notes:
This particular M3 was fully serviced under scheduled maintenance and meticulously followed thereafter with oil changes every 7500mi.
The VF540 Supercharger was installed at 92K. Now at 106K, the thirst for more power set in and a VF620 upgrade was scheduled. After some discussion, we agreed that an inspection was in order during service.

New vs Old Rod Bearing - Comparison
As seen, Connecting Rod bearing #8 suffered the most damage, with all remaining bearings showing considerable wear. Needless to say, prolonging this would have likely resulted in engine failure if not handled sooner.
