As I mentioned previously, I would only recommend using plastiguage to see which bearing shells you need.
When I’ve measured crank bearing face they come out as in photo, so std crank. Very minimal wear on this 100k crank , would have been ideal if bmw give you the option of shells as they do on main shells, especially for no 3 .
