Hows the setup? Has that car been running on the track you plan on attending? You have a friend that has been running? Don't let the frustration in the beginning get you down.
Usually a practice is held on a weeknight. At least the tracks I attended. Go to it this week. Then you get to run with a few guys instead of a whole field and the other drivers will help and you will have a little seat time before the big night. Watch the other drivers. Look for their break points on the track. Remember them. Ease into those break points. Meaning break early in the beginning. If not I guarantee you will go in to hot and will be facing the wrong way. My car I braked hard at the break point to set the car then slowly lifted so at the apex I was back to the gas. Dont fool with the setup in the beginning. Learn the car first. Run some laps. Right now you have no idea what it needs. Then make small changes one at a time. Like air pressure on one tire. Feel the difference.
In the drivers meeting they will tell the slower drivers to stay low on the straights if the leaders are coming around. Watch the flags he should tell you when they are behind you. HO BOY YOUR GONNA HAVE SOME FUN!
