Online Spring Rate Conversion Tool

boo-ya!

I got confused when I tried to directly convert lbs to kgs.  Googled and got this little gem.  Turns out its lb/in and kg/mm.  Makes a bit of a difference, lol.

Also found a chart..

And the math..

Sticky anyone?

well thats all nice and cool but i know for a fact that not everyone uses Kg/mm,  what about kg/nm, and there is other shit too... the whole suspension industry is so fucked... every manufacture has there own standards. pick you flavor stick with it. IE Bilistein, A1, just examples.

haha that is true bout other units.  Lots of other units.  I found some stuff like that when I searched.  I even found a chart for torsion bar rate conversion.  Anyway kg is the most common rate when shoppin for S13 coilovers and lb is just about the most common when shoppin for springs for the rear.

For a simple conversion, its 56lb/in to 1kg/mm.

ex. 350lb/in divided by 56 equals 6.25 kg/mm.
8kg/mm times 56 equals 448(round to 450)lb/in

Basically
6kg/mm = 336 or 350
7kg/mm = 392 or 400
8kg/mm = 448 or 450

I'm not sure if 56 is the exact conversion number, but it's close enough to use.

i have 600lb/in in the rear and its great... for drifting. not so good for comfort

in the front i have Cusco coilovers. i think the rate is 8k. feels good. any quality coilover for S13 will have a good rate
