Maybe you ask H&R in Germany directly.
Usually the springs on standard LAD are softer than normal ones. So maybe if the H&R are made for LAD, they might also be softer, but that is just speculation.
To find out if you have LAD is very easy, just check if the shocks have a hydraulik hose at the bottom.
I also sent you a link on the U.K. board where you can buy in Germany some used LAD shocks.
