I had those Maya's on my E55 (if they are STM's cause they look very close) and while they weighed about 24lbs they were softer than gooseshit... if you live in an area with good roads (which I think you do) they might work. The offsets are key- I had HRE 897R's 20x9 and 20x11 on my M6 and they will not fit on the M3...
