To many classes, to many engine choices and tires. Its all to confusing for a newcomer. By the time you start to figure things out you then realize that there is no way you can afford to spend the money others do to run up front. For myself the main thing is the tire game is just crazy. I just go with what i have and try to make the best of it and have fun with my son. But thank god for some of the people on this forum that have helped me out and given me advise on gearing and what tires to run at certain track (Even though i cant afford to own multiple sets of the same tire).
