ericnova- thats what the jack is for, it stops it from dropping too far. And as far as I know if I use a center coil it's shouldn't throw off the spring rate because the center coils don't really have any give to begin with, its all the outer coils, which is why I didn't want to cut one
1ownerT- cutting stock springs usually doesn't hurt much because they are softer to begin with. From what I've been told cutting stiffer aftermarkets is not a good idea. As far as thinner isolators I've been told using a piece of heater hose is my only alternative.
sqzbox, just the rear needs to come down. I put a pic at the bottom so you can see what I mean. I'm running 315/35/17's and they are about even with my 275/40/17's in the front. However my prefered Nitto street drag radial doesn't come in many sizes.
