Thanks for the quick replies!
I could work out the right length of damper and pushrod in CAD software by tweaking a bit... But what do you mean by rocker angle in balance? I had a rocker arm system on a monster truck once that had bad geometry (because I tweaked with it but forgot about the influence on the geometry), and in the last part of compressing the suspension it felt like the suspension became easier to compress than in the middle:

This happened at a certain point. If you consider the distance between the pivoting point of the rocker arm and the shock as a line, when the mount of the rocker arm to which the shock was mounted past the point where the two 'lines' were perpendicular, the event occured - the suspension seemed to become degressive. Is this an example of what you mean by 'rocker angle (not) in balance'?
