Some time ago I installed a set of lowered progressive springs with Bilstein shocks in my '67 122S 4dr. The springs are from a company in Germany named Buttkereit Auto Technik. They are powder coated in red with Buttkereit in black. After 2 yrs of use on a car that is only driven in the summer, the springs seemed have collapsed. The coils at the bottom of the spring are sitting on top of each other and the car seems to be much lower than before. Measuring from the ground up to the lower fender lip is 24.5" in the front and 26" in the back. Does anyone know what the normal height is on a standard sprung 122S ? The ride has also deteriorated, so I will probably go back to a set of new stock springs.
