If you're new to AX and track, then a standard alignment should suffice.

Once you get some experience and are comfortable driving faster/harder you'll need to get a "track" alignment with the maximum negative camber possible (typically around -1.25 degrees or so in the front).

Without this you will see very high wear on the outer 1/3 edge of the tire. See this thread for what can happen: http://986forum.com/forums/boxster-racing-forum/33823-need-more-negative-camber.html

The issue is that as you turn hard, the camber of the outer wheel increases and thus, places more pressure on the outer edge of the tire. The additional negative camber from the track alignment will set the top of the wheel inward to start and thus, will allow the outside wheel to stand up straight (as the camber increases) when turning and use the entire surface of the tire rather than just the outside edge.

When you get really good on the track, the stock alignment (even with max neg camber) will still be insufficient to mitigate the increase in camber during turns and then you'll either need adjustable camber plates or adjustable lower control arms to reach the level of negative camber needed to keep the tire flat during hard cornering.
