Designing sway bar - very upset!

[jsgprod]

Substitute (D^4 - d^4) for D^4 in your formula above and it will work.

D = outside Dia.
D = inside Dia.

I believe I got this from an old Steve Smith book. I just happen to keep that formula in a little notebook I always seem to have handy

Gents,

Another related question: What is the guideline for the ratio of spring rate to sway bar rate? I am undergoing the same exercise and don't eally know what spring rate to design the sway bar to.

And I guess as spring ate goes up, the ratio goes down???

FWD=(rear bar as big as you can get it)/more rear spring
