Cutting front coil springs 72 1/2 Ton

[Hawker7]

I took my front coil spring out this afternoon and would like to cut it so the truck will sit 1 inch lower in the front. The top of the coil spring seems to have a smaller top coil as it sits on a bump on the top a-arm so I assume I don't cut that side. I'm I to cut the bottom coil? If so, how much to equal on 1" of drop? It also seems that the bottom coil sits flat and if I cut anything off it won't be flat again. Don't know if that makes sense or not?? Attached is a picture of the bottom coil.
