I by no means am an expert on this, I track my car 12-15 times a year but have only been doing it 3 years so I consider my self still new to it.
1. I hate working on my car at the track, I'm there to have fun, drive and learn. Not play mechanic so I make sure my car is 100% ready to go. I do take some spares but very little and tools to get me by.
2. Tires should be no problem for you because your new at it. Most likely your not going to outdrive what you have on the car and if you do its a good learning experience in car control.
3. Important things.....Keep yourself hydrated, fed, and in the shade if you are in a warm climate like Road Atlanta in July. Take what you need to achieve that. I have a friend that shows up in her 944 with a cooler, a chair, sunscreen, tires and an umbrella. And low cut tops but........... I take all kinds of **** in the summer, ext cords, fans, head wraps, coolie hats.......It gets hot. Plan for it.
4. 4 things I use the most, tire gauge, torque wrench, 12v air comp, and a jack occasionally. Factor in fuel also, are you going to buy fuel at the track or locally? Plan for it.
5. Last.......I see a lot of people drive to the track that have mechanical problems and then spend the next 4 hours trying to figure out how to get home. We push our cars on the track and it does happen to the best of us. Research a local towing company that can take you home, a Uhaul truck and dolly, etc....... Don't get stuck on sunday afternoon saying WTF. Have a contingency plan, Be like Scotty on Star Trek and be able to go into damage control mode quick.
Hope this helps a bit.........PM me if you have any questions.
