Sorry for the delays, been tied up.
They are just like a stock 19" wheel over pot holes. I had no problems or issues. But I wouldn't drive into a sink hole.
The offsets are for a regular a 3 series, the spacers work with the M3. I will record and post the actual offsets, however, later today when I go back home.
Got a couple of interested parties, but need to move these out.
