Ok so I am the new guy here. I just finished putting Ground Control coilovers on my car yesterday. I started off setting them at the halfway point on the front. Now I want to adjust them on down in the back before I have my alignment and camber kit set.

I have read that you have to jack up the car to do this. I can understand how this would make it easier to raise it up, but I don't understand why this makes a difference when you are lowering them. After all how can I put it exactly where I want it when I can't tell where it is going to be until I let the car back down.

Also I read somewhere that the rear springs don't fit up into the perch until the car is let off the jacks. Mine does this, but it does fine once you let it back down. That really scares me, though. Is this normal. Will they not come out if I hit a bump. And why do the fronts do fine.

Please help me (and go easy on me)!
