They look about as expected for the mileage and year. Sleep better now that you have them done. What type of bearings and bolts did you replace them with?

That was my impression, not scary wear but as expected and happy to have it done. Shop used VAC kit for the replacement.

Ps. Looked at Mahle's S65 bearings at all as an alternative?

Can you link me to the MAHLE ones?

There is a quite extensive discussion with a Mahle rep on this board as well as on the UK m3cutters (Mahle is UK) which I found quite interesting.

Although BE made measurements and claimed the ARP 2000 provided better roundness (can't find this info any longer, seems they have taken it down?), the ARP 625 is certainly being used for the S65 by various shops. It is also promoted for the S65 rod bolts by ARP, which surely must be worth something. I personally wouldn't hesitate to have them reused but will be interesting to hear about your final decision and finding.
Ps. I guess you will be able to see on shells wear if the roundness is totally out of whack.

And again, really looking forward to some high resolution pictures on the shells!

Thanks

Looks like the S65 bearing wiki has been taken down .

Damn, that's a shame, so no receipts correspond to the ACL shells & ARP 625s?
Any idea when the previous owner bought it? (year/mileage).

Nope, no data

Here's mine which I just changed. 170,000km, 09 E90 DCT, original 088/089 bearings. Looked like the car had BMW service intervals for most of its life with a few exceptions.

Oof, they were in a bad state! But pretty much what we expect for those type bearings and with that mileage.
