CK out those air bag suspensions...that should allow you to drop it and still be able to drive it without dragging or rubbing. Old school guys will tell you to cut the front coil springs and remove leaves from the rear and put smaller wheels and tires on it to drop it.
if he bags it he will remove the springs completly from the front and still have to lose leafs
drop spindles and drop springs is a good place to start i wouldnt suggest hacking the spring unless you know how. there is no right way to cut a spring but there are better ways
buy the lowering block kits and lose some leafs u can go down to a monoleaf but i suggest keeping the load leaf (fat short one) you might break the single leaf if you dont and it cuts down on wheel hop
if ya wanna get fancy u can get an air bag kit or a 2 pump hydraulic setup
i recomend hydraulics faster and a hell of alot cooler
