I was just looking at this site:
and if you notice they now come in a new setup for the e90 3 series.
Whereas before you were either stuck with really high offset (et47 17x8, no lip), or 5 series setup (et20/et26 17x8 + 17x9, nice lip [due to the offset]), there is now a new setup:
et34 17x8 [comes on the e90s]
I'm really interested to see if these have a good enough lip. I've wanted these rims for a while but I only like it when they have a lip (usually requires low offset). However, I don't want to run too low of an offset because that would mean I need undersized tires. ET34 may just be perfect!
Pics? I may just buy your set too.
EDIT: So far I found these pics, damn not too much of a lip but I think these might still be winners:
...quite a difference from the ET20 17x8 (this guy is running it on front and rear) setup, notice the massive lip:
