Question about spring rate

[cheehong]

any body know what mean this numbers " 250/40" or "250/30" that print on the spring?
how to calculate/convert it in the kg/mm unit?
thanks....

this might be like this... 250 stand for length, 40 stand for spring rate.. might be 250mm in length and 4.0kg in spring rate... this is already in kg/mm unit.. if u put 4kg then the length would to shorten 1mm... if i'm not mistaken.... du a test on the spring c wat i say is correct or not...

yup...ur rite...250/40 and 250/30 is length/spring rate

length is in mm while spring rate is in kg per centimetre...

btw...r u using rg? wira/satria? the figure sounds familiar

wow...buddy...ur body made of impact absorbing foam kah? jk, anyway i used that b4...can even push it down...i drive satria 1.6, i think that its stiff enuff adi...wuts more the rg suspension they dont really tune the damping rate good enuff...cant set the ride very low...macam naik kuda...hahaha...i think it should be okay if u change to 5/4, but prepare urself to the meaningless talking of the rg marketing man...to him...any probs...its ur car not my suspension
