Air, it's gotta be air. My 34 gets to within about 2" when I let the air out. Of course you can't drive it that way but it looks cool. You can always use dropped spindles, blocks for the springs, etc. A friend of mine has a really radical Ford pickup that uses a mustang II front end with dropped spindles. It wasn't low enough so he lowered the body on the frame. I'll get a picture and post it. Probably the only one like it.
