Forget Vogtland, it's too soft and will crash, I threw them out as trash a few years ago. I had them with Bilstein's HD.
These were replaced with Eibach Streetline (not sure if this is right but the ones for road use not track use), pretty good handling and a little on the firm side but no problems with bottoming out.
Bilsteins wore out and now I have Eibach Eibach springs with standard Boge shocks. Much softer than the Bilsteins, handling not as confidence inspiring as Bilsteins but no major problems still can "bantai" the corners with more body roll. And still manages the lowered look. A point to note with this combo is that you would have to cut and rethread the absorber shaft for the rear else when you jack up the car and lower it again you have to make sure the springs sit properly. Not a major problem if you don't do this either unless you take the car rallying.
