I have a set of BBS 16x8 et11 on my 123. Perfect fit in rear. On the front, a slight poke. But I like it.
Sometimes folks run a staggered et11 and et23 to prevent that slight poke.

Now I've also ran a set of 15x6.5 et37 8 hole Mercedes wheels with cheap 10mm spacers. Not too bad, but I do think it was pretty wide and should be run with hubcentric type spacers. Definitely needed longer bolts.

I would imagine with the wider rim, 7 vs 6.5, and the et38, you'll need a wider than 10mm spacer to clear the front tie rod.
