Stock springs?

According to your profile you have a 93 GXE, so my answer will apply to 3rd gen GXE's. Note: the only place to obtain accurate information on the suspension is the FSM, which has all the spring rate/dampening data. The following is from the manual, and not a butt dyno.
None of the springs are the same between the GXE and SE (with the same VG engine). The rear springs are different, but have the same spring rate. The front springs in the SE are 134 in/lb, GXE 114 in/lb. Front sway bars are the same. Rear sway bar in SE is 1.2mm thicker (stiffness goes up at the square of the diameter, so figure 15-20% stiffer).
The dampening rates on the SE are much higher than the GXE. In the front the compression rate is 1.63x, rebound 2x. In the rear: compression 1.3x, rebound 1.5x. I have no idea which, if any strut (SE or GXE) aftermarket mfgs try to match as a "stock replacement", since they are so different. I suspect aftermarket ones are closer to SE struts.
