== Spring Rate Calculation ==
If you want to have your own springs wound, here is some information for you...
* The formula is:
k= (Gd^4)/(8(D^3)N)
* Where:
d = wire diameter
D = spring diameter
N = number of active coils
G = [http://en.wikipedia.org/wiki/Shear_modulus Shear modulus] of material, For steel; G = 79.3 GPa
Take your tape measure and check the diameter of the coils and you've got everything you need.
The EASY way, would be to plug in the data [http://www.iroczone.com/calcs/chassis.htm here].
A bit more exacting formula can be figured out from the information on [http://www.engrasp.com/doc/etb/mod/stat1/spring/spring_help.html this page]
