That is a tough call because drag racing and handling generally require different parts. A couple of things they do have in common is better bushings, LCAs and maybe a set of LCA relocation brackets.
Better tires will help but once again drag racing requires a set of soft side wall tires and handling requires low profile tires with a stiff side wall.
An adjustable panhard bar could help in both styles of driving, especially if the car is lowered. I have found that the factory bar bends easily and allows the rearend to shift around a little. I have also noticed that the rearend may not be centered under the car from the factory.
Shocks/struts are different depending on your style of racing. Even the size of your sway bar is different depending on how you want to drive your car.

I agree with the previous comments regarding setting your car up for drag racing. You will want to go with stock springs or drag springs not lowering springs. Also boxed or aftermarket adjustable LCA's along with LCA relocation brackets are recommended. Also an adjustable panhard bar if the rear end is indeed not centered. An adjustable torque arm will allow you to adjust the pinion angle of the rear end and help with wheel hop on launch if you are experiencing that. You can also disconnect the front sway bar links or remove the front sway bar to help with weight transfer. But reconnect them if you are dirving it home from the track.
