How much have you researched the rack? It's your car and money, but in general racks, especially in A-Body cars tend to cause more issues than they solve. Unless the car is sitting on an aftermarket frame designed around a rack, you sacrifice suspension travel and turning radius, while making the bump steer issues in the suspension worse, just for better on-center feel.

If the car is only being used for drag racing with mild on-road cruising, that's typically fine and the weight reduction is certainly beneficial. If the car actually needs to be able to turn though, you're almost always better off with a quality box on a stock frame A or F body.
