Can someone help me explain why we are running spring rates in the 600-1000 lb range for a car with such low wheel rates?
I was shopping around for some new dampers and sprung a conversation with one of the suspension guys. I was targeting 600F/800R rates on my Stohr FB. His initial reaction is that it's oversprung by at least 3 fold. He's thinking at those rates the damper isn't providing much mechanical grip and is behaving more like a roll bar if anything. To the point that changing dampers won't do much as the spring is way to stiff.
So I started searching around and found the formula which correlates spring rate, wheel rate and motion ratio. Based on what that is suggesting, I should be running in the 200-300 lb range.
Can someone set me straight?
