If you'd like to keep the stock M-sport / standard suspension but you find the car to sit just a bit too high over the front wheels; here is your solution:
Switch the top front spring seats/plates!
They will lower the car about 10 - 15 mm (0,4 - 0,6").
Part number is SUFT015 and the company manufacturing them is Supersport (Germany):

Mine were about 60 USD (shipped - within Europe).
How? This is how:
Follow larryn's (http://www.e90post.com/forums/showthread.php?t=15397
) excellent DIY on how to replace the stock springs with H&R's; starting from post #5. Follow steps 1 through 17. At step 17 I used a socket with a 21mm outside grip together with a 6 mm Allen key, this to prevent the shock absorber piston rod from rotating.
When the original spring seat/plate is removed, simply replace it with the Supersport one.
Reassemble in the opposite order.
Below you will find few photos from the installation. Sorry for the not-so-professional DYI layout...
