I'm a bit clueless with this wheel fitment stuff at the moment, as you can tell.

Offsets that significantly differ from those BMW engineers specified substantially compromise suspension system kinematics and dynamics and are therefore something to avoid.
Focus should be on reducing wheel weight by choosing a very good forged wheel, with all other specs being identical to factory.

Bottom line: Keep these cars production line stock unless you are certain (though loads of research) that the considered mod will indeed improve the vehicle overall.
