I think you can just cut your coils down and be ok. This is what I am trying right now. I removed one Calmini spring and my dad took the Calmini spring and the factory spring to a custom spring shop and the guy there analyzed them with his CNC spring machine. Turns out that the Calmini spring is barely any stiffer than the OE spring, this would probably be because the OE spring is 9/16" diameter steel and the Calmini spring is 5/8", and the Calmini coils are wound slightly closer together.
What this means is that the Calmini spring is simply too long for our 2.0L applications, not too stiff. I think Calmini designed the spring to be long enough to absorb the weight of the 2.5 V6, plus skid plates, plus a big heavy winch bumper, and still have decent amounts of travel. However, without all this extra weight, our little 2-liter beaters simply don't have what it takes to compress the springs enough to overcome the built-in preload of the springs. The only thing holding the springs in the vehicle is the maxed-out struts, really. So my conclusion is to cut the springs down by 1 coil. I tried half a coil on the driver's side and it didn't make a huge difference, but I think a full coil should be just right. I also tried putting the factory spring in just to see where it sat in the strut's travel range.
The difference between the factory spring and the calmini spring is huge though. Even just cutting half a coil off the Calmini spring makes it A LOT easier to install the spring. An untouched Calmini spring definitely requires spring compressors to install, whereas with half a coil cut off I used a prybar to keep it in the lower bucket while my dad jacked the A-arm up. With the stock spring I didn't hardly need to use the prybar cause it slipped in so easily.
3stagevtec, I'm sure Jeff will sell you some custom spacers.
