I'm trying to compile information on the different spring rates for various springs/coilovers specifically for the Accord/CL/TL. So far I have this:

Endless Zeal B6 - 12kgf fronts and 9kgf rears
Tein SS - 7kgf fronts and 4kgf rears
Comptech - according to Comptech they are 10% stiffer than stock
Eibach -
H&R
NEX Coils -
Apexi WS Coils -

And also does anyone know the conversion of lbs to kgf? Thanks!
