~1" torsion bars, XHD springs in the back, front and rear sway bars, Bilstein shocks. Also add subframe connectors if you don't already have them. Alignment should be around -.5 degrees camber, +3 caster, 1/16 to 1/8" toe in. Factory alignment specs are for bias ply's and are horrific for anything else. Modern tires will also make a huge difference, and I don't mean BFG T/A's.
