I just got back from BMW Dealership with M Performance HAS installed and 10 mm spacers front and rear. My settings are currently as follows (see photo):

Front: 606 mm
Rear 598 mm

This setting is waaaay too low. I've already made my first scrape on my front lip just going up my driveway.

The factory recommended settings for 20" wheels are:
Front: 633 mm
Rear: 626 mm

I will drive the car about 150 miles for a week or so, to allow the springs to settle as recommended by the BMW tech. I'll then go back to the dealer to get the height to 625 mm (front) and 615 mm (rear) and an alignment.
