If those X6 wheels are oe, they have
different front/back wheel bore sizes:
those rear wheels have the
same bore as your X3...72.5mm.
However, those X6
front wheels have a 74mm wheel bore, (like all E70 X5 wheels), and thus the front wheel bore is 'too big'.
Some posters have reported that they got away with using hub centric rings for the larger bore wheels, but that is not my recommendation.
Your best bet is to find X3 or X5 E53 wheels you like, or replicas, if that's your direction.
