what are your tire sizes? And what size are you wheels..
If your wheels are staggered they should be 19x8(+37)/9(+39) tire sizes should be 225/35/19 and 255/30/19. You want and aggressive stance all the way around and not just in the front or back so you would want to put them on the front or back...or the wheels won't look even.
Spacers are a cheaper way to get a more aggressive stance. Depending on your tire sizes, 10mm-15mm spacers in the would look really nice and would be pretty flushed. I can't remember the exact specs for flushing out an e90, I know they have a little more clearance then the e92.
