My bad, listed wrong units initially. It's 2N/mm helper and 260N/mm main spring, AC's input is in N/m so by magic of metric unit system they become 2000N/m and 260000N/m respectfully. So all extra 0s are already there and all confusion comes from a fact that car is indeed uses spring which you can squeeze by hands. This project was fairly long in development and was tested by a person with direct access to real deal to confirm details and it was given a green light.The helper spring is there to keep the main coil located up against it's perch at the top of the unit, in max suspension droop conditions (big jumps, on the jack etc).
That aside, there are some factual errors in your reply, @PJohann. No offense intended.
Spring rate is measured in Newtons Per Meter (N/M), where it describes the force required to compress the a spring with that rate, 1 Meter, and not NewtonMeters (NM) which is a unit of torque (ie a force in Newtons acting at a distance in Meters, to produce a twisting force; or Work, measured in Joules (1J = 1NM) where a force moves a mass through a distance.
Also, I think you may have misread @Beezer215's post.
A spring rate of 1336 N/M is like (roughly) what you would feel deadlifting 134Kg. Put one of those springs at each corner of a car, and four fat asses like me would compress those springs by almost a meter. @Beezer215 is (correctly) suggesting that you add 2x zero to the end of the spring rates 1336 and and 1093, to produce spring rates of 133600 N/M and 109300 N/M, which are softish, but right in the reality ballpark. Look at the bumpstop rate, for example?
The ;2 part cannot be usefully describing a 2N/m spring rate. That's (2N) the gravity force you would feel holding a 200g box of Smarties. The main spring weighs more than that, and would simply crush the helper and drop off it's perch. That value has to be something else. (Or also requires adding 2x zeroes, which would make it like a 20Kg weight. Yes, that would work. Doesn't explain the similar appendages after the bumpstop rates, tho?
So unless AC has some special "divide by 100* shorthand for some values (like, the spring rate, and not the bumpstop rate) in the INI files (which I haven't seen digging through them), to save on characters.... I think @Beezer215 might have a point?
