If you are going to be rebuilding the suspension, your most bang for your buck (free) will be to cut the springs. Americans have been cutting springs since hotrodding was born; and, despite the admonishments of some...there is only one drawback: unlike a haircut the spring length won't grow back. Use a cut-off wheel in an air tool and it'll slice the end off like a butter knife. It will not create enough heat to become an issue worth capitalizing. Also, you can use a soaking wet rag on the "to-be-saved" part of the spring and it won't get hot at all. Use the tool to grind off any jagged edges, especially where it will fit into the mounting donut.
Take 1/2 of the top round off each front and rear spring and re-install them. Let the car settle by driving it for a bit and re-evaluate the height adjustment you've made. The good news is you'll have a lower stance...the bad news is you will introduce some negative camber...and the admonishment about bottoming out will eventually come into play.
Keep taking off 1/4 rounds till the car is suitably cool looking. This trial and error method will make you a suspension-putting-together expert. Another approach is to fill the wheelwells with higher aspect ratio tires. You may end up mixing and matching spring cutting with tire sidewall height changes til you get it where you want it. It is...afterall...up to you.
