You can't calculate the motion ratio from the info in AC suspension files, so no.From the work you`ve done before and the credit that you receive from many modders I am sure that theory is no problem for you, but did ever crossed your mind that Kunos in all their wisdom implemented the correct formula behind the scene and left for us in *.ini files the easy possibility to enter the correct real life data? In that case the formula if applied twice will give the resulting weak suspension. Out of curiosity only
Kyuubeey how did you arrive at the exact number for the motion ratio for NSX smaller than 1? And what`s wrong with this formula apart from the practical difficulties of measuring damper angle from vertical and calculating installation ratio separately for front and rear wheels?
And an MR smaller than 1 is very typical; higher than 1 is only possible with a rocker arm or similar (think openwheelers and LMPs). So the wheel rate will almost always be significantly lower than the spring rate.
