Pics will follow tomorrow as it's been out of service today for another project....
Overall ride comfort is pretty similar to stock (slightly stiffer in Comfort but not hugely noticeable with 20" wheels, drove a F10 M5 with H&R and 21" wheels which felt much stiffer in comfort mode).
So far I have to admit the kits from H&R, AC Schnitzer and Hartge are very close in ride comfort.
Handling has not changed dramatically either , slightly less body roll .
If you stick with OEM wheels you might want to consider spacers to create a more flush finish (I am going to HRE wheels soon so didn't worry about spacers for a few days/week) , probably somewhere around 5mm-10mm should do for the rear and 5mm-8mm in the front , I am assuming another more than 10mm might be too aggressive and cause rubbing in the rear.
The Hartge springs retail for ~450 Euro in Germany (http://www.hartge.de/e/bmw_fahrwerk_6571.html)
