In the Mercedes Service Manual for Chassis & Body, Volume 1 there are some spring specifications in Group 32/Job# 250/2. It lists the part number; Spring Displacement at 1000 N load; Coil thickness "d"; and Test force at spring length (in N and mm). Now to my question: is possible to determine which springs are longer/shorter and softer/firmer by the table provided? I would think that given lengths, a higher test force would likely mean a stiffer spring rate. As always, all input is appreciated.
