ok i have 3 sets of coilover i could get from a friend now what spring rate would be best for my 95 4 door gsr ..as for now its will be goin on stock shocks/struts..then maybe goin on kyb agx or koni reds or yellows. This set up will be use only for daily driving with baby onboard. so i need that smooth ride, or not to much of a boucny ride and dont want it to bottom out alot.. maybe will be a 2-2.5 drop front and 1.75-2.0 on rear.. spring rates as follows:
GC
350R 300R
400R 250R

omni sleeves
448F 336R

Thanks

 

I have 275 in the rear and it is kinda a rough ride. The rear spring rate determine your ride quality the most. I wish i had gotten the pro kit with progressive spring rates. So my advise to you is the softest rear spring rates(~200) and about 350-375 in the front. That should be pretty good.

BTW on your post you have R on all four GC. No fronts???

 

Handling characteristics, usage, and current or future mods have the greatest effect on what spring rates you should get. If you're planning to only to shocks/ springs, go with the 350/300, if you're going to do the rear swaybar, go 400/250, and if you want to track the car, get the omnipowers.
