If you want to take it a step further you can use a slightly stiffer torsion bar and delrin lower arm bushings. They offer less deflection, longer life and quieter operation. The heavier t bar is usually necessary to avoid oversteer. Most guys tend to use too much rear spring or have the rear center of gravity too high. Adjustable shocks are a nice tuning aid but I recommend looking at mono tube type if you decide to spend the extra $$.
