I see you're in MD, so am I. I do about 10 track events per year and instruct with NASA and SCMC. What group are you going to do a track event with?
If this is your first track event, your car will be fine as is. Once you get some experience you will have to make some adjustments.
Here is what I would recomend:
1. change your brake fluid out to a better brand. Any synthetic Dot 4 will be good for now.
2. Check your rotors and install some better pads. Send me a PM I have a few different brands that I'll sell cheap that will work on the street and track, so you don't have to swap them out, and are much better than stock. I have outgrown them and my car is pretty much track driven only.
3. Since you are scheduled for a tune, have your OT tune be a little on the rich side and pull a few degrees of timing, that will help keep your car cool. Excessive Motorsports, in VA, did mine and I have very happy with it.
4. Do a general inspection and maintenance of your car. Be sure your belts and hoses are in good shape as well as brake lines and seat belts.
5. Don't forget to have a SA rated helmet. Many organizations will not allow use of a M rated helmet.
If you are staying close to home, the closest track is Summit Point. I'll be there with NASA in April, if your interested.
