Last year was my rookie season - no previous racing experience, much less on the Salt. I found several things helpful for my effort. Read the rule book over and over and over again. Follow all the old threads on this site that you find to be relevant; lots of good info here and leads to other things you need to learn more about. Get in touch with the appropriate SCTA guys that can answer your questions; see Section 16 of the rule book. Network in your local area to find a fellow racer; have him/her do a walk around on your car to spot those little things that might trip you up on your first run through Tech. Put together a crew that is knowledgeable and that you can have fun with. After that, "be safe, go fast, and have fun!"
And what are you going to be running? What stage are you in your build?
