Just one question, is the spring rate calculated the spring rate at the wheel or the actual spring rate?.
It's calculating the exact some numbers that are in the manuals graph which looks like spring rate at the wheel. (vertical force / vertical displacement of the wheel)
I received the equations from Oleg so there accurate. Same goes for the sway-bar values on the swaybar tab.
Note, there's a SPR01S and an SPR01 tab depending on the spring your using.
