Q: 05 M3 wheels on Benzo C350??
Lessee, what could go wrong.
Well, the most obvious thing is offset. Then, there are the wheel bolts, too long or too short or the thread pitch might be different than the MB's hubs. Or, the wheel bolt seating surface may well not match your MB bolts. If you were a member of MBCA you could read an article on this very question in the current issue of the STAR.
It's also possible that the TP sensors might not be usable.
That should be enough.
I have seen some shops put BMW wheels on a Merc, so it can easily be done. The concerns become offset, getting the right bolts, etc. but that is normal. If I had a spare set of HREs, I'd give it a shot. You may also want to see how much HRE would charge to rebuild them (if 3 piece).
I'd contact HRE. They have been great with others.
