Need handling help..

Sway bars to start, Larger torsion bars 1" min, good shocks all around (i.e. Bilstein, Hotchkis, Viking, etc.) wide & short wall tires so plan for 17" and up wheels, modern tire alignment so QA1 or equivalent upper A Arms or offset bushings, adjustable strut rods if you really want to dial in the front articulation, and at least 11.75" OEM brakes if not Dr Diff 13" fronts because stopping is part of handling.
