I'm currently running OEM style 24 wheels on my E36 328i convertible. It's recently been lowered, and now the offset doesn't really look that awesome. On my E46 I used wheels wider wheels with a more extreme offset which did wonders for the looks.
On my E36 I really wanna stick to the OEM wheels (so, 17" 7,5J and ET41 with 225/45 R17 tires) but I wanna space it out a bit to fill up the fenders and make it look better. I kinda wonder how much of a spacer I can safely use without rubbing on my OEM wheels.
