OTS ground control spring rates wrong?
got my gcs a few days ago... i ordered the OTS gc's to accomodate tokico blues for my 92 lude... all 4 springs tho have the same spring rate of 67 (im guessing that is in metric terms)... and if im correct, that translates into english lingo as 382 lbs... for OTS spring rated gc's though, shouldnt the fronts have a higher spring rate then the rears instead of equal on all 4... whats goin on?
from what i read, having a higher spring rate for the rear (in this case being equal to the front instead of less then, just as how it should be for ots rates) would in fact incrase better grip and less under/oversteer... would i be correct in thinking so?
either way... having all 4 in equal spring rates would indeed be a little bit sportier handling wise then having a smaller spring rate in rear and larger in front right? ... so its a win win situation for me if im ignoring the fact of ride comfort right? thanx guys

not sure if they were supposed to be the same spring rates front & back, but here's my take:
stiffening the rear will push the car more towards oversteer [or lessen understeer]. my tokico illuminas are set full stiff in the back and the tires have a little more pressure than the front, which are set one step softer than full stiff. the idea is that the rear [rather than the front] will be more likely to drift slightly, rotating the car easier. of course, you wouldn't want to over-do it. it's all just compensation for a car with crappy weight distribution.
not sure, but I thought I read that some people use stiffer spring rates in the rear than in the front.
...and who cares about "comfort"? comfortable is just a fancy way of saying "slow".

It's not so much which would be 'sportier', it's just that there is a difference handling wise. The difference comes in the drivers ability to take advantage of the differences, and they are very small at that and each setup requires a slightly different driving style.
Having equal spring rates will generally promote oversteer, it's up to you to decide if that is 'sportier'. Some autox folks like the spring rates higher in the rear and others don't so there is no "right" answer, only the one that you prefer.

im not familiar what GC gives for preludes, for civics and integras its like 350F/250R. you can call them and check to see if what you got matches their specification.
really, the beauty of an adjustable coilover kit is you can customize your suspension now. unfortunately, having all 4 of the same springs doesnt allow you to do any spring tuning of switching front/rear rates. but you can always buy a new pair and see if you like that.
yes, generally ppl have found raising the rear rates increases oversteer. whether its appropriate for you and your application, is going to be up to you.

If I recall there are all sorts of numbers on the GC springs. The number 67 is interesting. Could it be the diameter? 67mm ~= 2.5"
you can read my faq on how to discern the spring rates from eibach race springs, metric or english.
