To prevent further tire wear 1. Front camber kit 2. Polyurethane tension rod bushings or adjustable tension rods. 3. Rear camber kit 4. 4 wheel alignment at a "real" alignment shop
For additional better handling 5. Springs 6. Sway bars
If your shocks are shot you might want to replace at the same time as the springs. Stock shocks are fine and fairly inexpensive.
