And one thing to consider is racing in Mexico, Brazil, or another Latin American country where they are crazy about road racing. The challenge in America is that most people who are into racing follow NASCAR. Don’t get me wrong, there’s lots for any racer to learn in any series but the path to a professional auto racing career in the US is pretty much – midgets > sprints > late models > stock cars. If you want to do that then I would suggest getting involved in dirt oval racing now rather than running sprints.
Another thing to consider is how much you can learn from good racing simulators. You can get a lot of seat time, and learn a lot about car setup from these “games”.
One more thing, start making your contacts early. Get to know your local business owners and try to convince them to sponsor you. If you’re comfortable asking for money, and you can deliver value for business owners you’ll have a lot better chance of making it in the long run.
