Heated Lowered Springs?

[kombreeze]

Ok for years I've only dropped cars by either direct replacement or cutting of the springs. Most of the time I would springs from a full size sedan to install in a compact to insure ride. Well Im about to buy my springs and I'm trying to figure out what kind of drop can I get away with so the million dollar question....I can't beleive I'm asking but I actually have never done it....How do I heat the springs to lower the truck. They are uneven do to spacers installed between each coil so I know I want to lower just don't know how much so I figured why not just heat them and play a bit. Temporarily since I'm converting to disk durring the summer and since I'm buying a new house the budget just got tighter. I've got a theme and I'm sticking with it...
