Here is my dilemma.

A 1972 Mercedes weighting 1705kg has stock springs rated at 335lb/in front and 350lb/in rear. This sounds extremely high for a stock spring on car that was designed to be as comfortable as it gets. For example, 850CSi weighting 1890kg has 160lb/ft springs in the front. Any idea why there is such a big difference in spring rates? Does suspension design matter in this case? A-arm on the Mercedes and McPherson on the E31?
I think the Merc ones are softer: 335lb/in as opposed to the 160lf/ft in the E31.

Inches and pounds--huge difference.
