I too have Spax adjustable dampers all round. When setting them I followed the Spax instructions and started with a low setting maybe four clicks in. I then drove a few miles and increased (front ones in this case) and repeated all the time checking ride comfort and nodding of the bonnet. At around twelve clicks in (out of 28) the nodding stopped and you could feel dampers doing their job. It was like a sweet spot had suddenly been found. Surprisingly to me despite the firmness I found the car was riding bumps in a more comfortable manner. I backed off a click as recommended and called it a day

René, you may have difficulty setting yours when you get them. This due lack of bumpy pot holed roads in Germany. Over here we are so lucky to have them everywhere
