Hi Jacob,
Welcome to RJ, how old are you? As 3D said, most of us have been doing this for a long time. If you have never made a pass in a race car it is very exciting!
There are many ways to get started. Save your $$ and go to one of the many schools out there to learn what our sport is all about. It does take a lot of desire, and CUBIC $$$ to run any type of car anymore. Read what you can, learn as much as you can about the cars we race.
There is nothing that is easy in this sport! When you speak of class racing, it is one of the most competitive ways you can race. Just like bracket racing, you need to run on your dail in, cut a good light, and take the finish line. You may win or lose by .001
There are many people on RJ with the experiance to guide you. But it does take more than just having a desire to race. Follow your dream, and work hard you may just accomplish your goal to drive a race car.
