i agree with you guys go with cheap springs from ebay or a true coilover system..never cut or heat because i've heard of springs actually snaping on people and causing accidents. plus if you want to have decent tires on your ride you're gonna need camber kits. if you lower it just a little you could probably sneak by with little or no tire wear but if you slam it, kiss the inside of your tires good bye.
final thought - if you have the money do it right, if not go with an ebay coilover system but get camber kits.
