I got a list of super old swaybars with diameter and lbs/deg. This DOES work but I will have to measure the arm length of the swaybar, the arm length where it attaches to the LCA and try to calculate the roll rate / spring rate at the wheel and this I wanted to avoid.
And no, nobody could tell me yet what roll rate their swaybar have. Weird, I would think if you produce something like that you at least calculate it once...
I will try then today to measure the geometry and let's see if I can find out the average roll rate of a 1 1/4" swaybar.
I need this for my suspension calculations...
