Hello, has someone from you already had the springs changed at the Smart 451 1.0 and has pictures of it? I had all the springs and dampers changed at the 451 1.0 71PS suction cup (EZ2008). Was not it necessary to change everything but a new chassis, because I liked to drive with the dwarf and he poltert in bad road conditions (I know, is typically tight the cube, but nevertheless). I had chosen Eibach ERL springs and Bilstein B4 dampers. When the parts arrived, I unpacked all the parts and checked the items (e.g. R10145) because I had bought them in the net/ebay and had to be careful there. Anyway, the Smart is now quite high. I did not want the Eibach lowering springs, because they had to be registered and secondly my mother also drives with the car now and again. The ERL springs serve according to Eibach as a standard replacement. Clearly, they will still be set up, but as if the height springs were fitted, they would have to be used properly.
