It depends on what track stuff your going to do - circuit or drift? Have you done any track stuff before?
We are currently setting up a drift car and our advice to our customer is to go with a basic setup - adjustable coil overs and sway bars. It also depends on the condition of the existing bushes in your car. The main thing is not to go to an extreme and buy every adjustable suspension component you can. You will be overwhelmed with adjustments. Figure out your driving style first with the basics and improve the car from there.
