The biggest key to racing is M O N E Y! You can go racing fairly cheaply, but even go-kart racing costs bucks. I spent less running my street stock for 1 year than I did on my go-kart. Step one is to find your local race tracks and see what is going on. Unless you can talk someone into letting you drive their stuff (highly unlikely) you will wind up buying your own car or kart. Getting started from scratch is the hard part. Once you're in and on the track, it's all about taking care of your equipment, learning the ropes, and making friends and connections who can help you succeed.
