Leaf spring question for the road race guys...

I don't have any experience with ss springs.. But I am interested in seeing how all this goes..

To be honest My duster handles pretty awesome with just the big swaybar an alignment and poly front bushings. It is really predictable even breaking loose, though a little soft. It really depends on How "all out" you are planning on running. If you just want to drive it you could look into the drop hangers like autox said.
