So how bad were they? Place your bets.
After a decade on BMW M groups and forums, I've found the rod bearing dilemma to be excessively religious in nature.
I trust in science.
In this entry, I document my rod bearing service on my original S85B50 engine: I briefly lay the fundamentals to bearings and discuss the rational for my bearing & bolts selection, along with the signature picture of the original bearings
Enjoy,

ACL Racing Series
Australian made.
ACL is recognized as a premier brand throughout the motorsports world and engine builders.
Their coated bearings combine ACL’s tough RACE Series lining and overlay metallurgy with Calico’s CT-1 coating.
CT-1 is a Dry Film Lubricant coating that helps reduce friction and abrasive wear. It provides intermittent dry lubrication and is not affected by dust or dirt.
It's what I run in my M engines.
