D. Clark,
I have seen your car around town a couple times.
I assume you have seen my build thread:

The simple answer if you want your car to really handle is Mike Maier Inc. There are lots of other upgrades you can make that will improve handling if you don't want to jump in with both feet.
The first things I would recommend are: swaybar, shelby drop, power steering and then a coil over kit or good shocks and 620 springs.
