Re: C1 - Weight distribution and spring rate

You have to multiply the wheel rate times wheel vertical movement from the point where the suspension begins to compress the spring, which will probably be about double the actual spring compression due to the leverage ratio.

Re: C1 - Weight distribution and spring rate

Hi Duke -
Isn't that the "330#/in at spring" vs. "110#/in at wheel" relationship, or is there more that I'm missing?

Re: C1 - Weight distribution and spring rate

You multiply spring rate times spring compression to compute spring load.

The load at the wheel is wheel rate times TOTAL wheel movement from the point where it begins compressing the spring to normal ride height. You would have to disassemble the kingpins to determine where the control arm actually begins compressing the spring as there is some compression at the rebound stop.

As far as the total spring loads are concerned, I can't account for the discrepency between "spring capacity" and vehicle weight, but I don't think it's something should be concerned about vis-a-vis spring durability.
