This isn't my idea; credit goes to Rickady88GT. I finally had a chance to drive my car yesterday and this mod is exactly what I was looking for.
I took two coils off a set of 1986 GT front springs with a 4.5" cut-off wheel (cut slowly and cool often) and installed. That's it. It lowered the front to just a slight nose down attitude and upped the spring rate around 20%. Nothing you can feel short of hitting a pothole. I installed a set of heim joint sway bar links at the same time so it's hard to say how much the springs did for cornering, but it turns on rails now.
I paid $30 for the springs and the time to do the mod. I'm a happy guy!
