Agreed with M41. Your best package will be Base with sports package. Also, you need to tell us what kind of tracking you're planning to do and how often?
All you need is a Oil cooler, better brake pads and if you have the $$$ a better LSD. I'm assuming you'll drain all the fluid with better synthetic stuff (brake fuild, engine oil, diff fluid, etc).
Other than that, it's ready to hit your nearest track!
