Thank you; is it counter-clockwise for 'up' adjustment?

I've seen other forum members say they think the M3's lights are aimed too low even compared to normal 3ers. Two full turns in the up direction seems to satisfy most of those people. I personally have no issue with it but there you go. Also note that the driver's side headlight is SUPPOSED to be lower than the passenger's to make it easier on oncoming traffic, so don't try to make them even; that's by design.
