I was wondering if anybody ever came across this site or something like it. Could it be possible to work something out that would fit a Justy to increase handling characteristics, lower, or raise slightly? I dont know a lot about spring rates and such, maybe some input on spring rates could help a lame-man like me figure out a plan of attack. speedagency.com/tein/tein_springs_standarized/sm05001250/i-35289.aspx-T

yah this could work.
its actually way more common than you might think. youd need your top and bottom ID/OD and the length and the rate you want. i will suggest a stiffer front than rear spring to keep it understeering as opposed to over steering.
call eibach and see what kind of stuff they can do for you. custom wound springs arent really that much.

No, a boxer will not fit in a Justy.

Wiki says curb weight of the justy is 1950 lbs.. Does anyone know what the spring rates are for front and rear coils? I tried to figure it out using a spring calculator and for the fronts I got about 200 lbs per inch, and the rears 275 lbs per inch.. I'm not too sure this sounds right? Especially with what streetruler suggested about the front being stiffer than the rear? I don't really know too much about this so I was hoping another member may have done this work already. Thanks!

i think the factory springs are right about 225lbs each front ant 200 rear. remember that sporing rate is the force it takes for the spring to be compressed 1 inch. in most cases....or the force to compress it 1mm. but most companies can deal with either measurement just fine.
for reference, my 2800lb prelude sport springs which were progressive, not linear, which is something to know, were something like 425 front and 375 rear from H/R.
I was thinking about this last night and id go with soemthing like....280-300 front and 250-275 rear. but keep the difference decent or you are going to wind up with neutral throttle oversteer which is really odd in a front wheel drive car. its virtually uncontrollable.
last thought, subaru uses a weird spring thats really wide in the middle and really small at the ends. i think rather than making a spring progressive by changing the spacing between the coils they do it with diameter of the spring. so keep that in mind. also i think they are going to wind you a linear spring rather than a progressive one so the ride is going to be a little less comfortable but it will handle better.
good luck...lemme know what you come up with im sort of interested in this idea.

second input. i just read on the s2000 website that skunk 2 uses a 240 something and a 380something. spring, but we use the same spring rates at all 4 corners
