I managed to get it lowered by 'just' 5mm. My dealer couldn't go any further since the car is being supplied by BMW UK and they needed to report back to BMW that all checks and settings were as they were supposed to be. I might be able to get them to take it a little further once I've had it for a few thousand miles.

Next step is to get the front windows tinted to match the rears, then I'm still considering the resonator mod.
