Well, I cut the front springs in my suburban, i cut 3/4 of a coil off to drop the front about 1 more inch. I had already lowered it 4"... I cut, because I have seen heated springs colapase after some time, and if you want to cut aftermatrket springs, most of the time it will only be 1/2-1 coil and no more..

this is not the first time i cut springs, nor will it be the last, but i have rode in heated springs and hated it...
