I have a feeling that someone is gonna drop a big "Try the search button" on you. I'd say look up topics involving shifting mostly, that's about all it comes down to, launching and shifting. Also, certain mods will help, like sticky tires to help with the launch...other than that, you'd be getting into parts that increase horsepower and handling. Well tires do improve handling, but if you want to keep everything mostly stock, they'll increase your chances of winning because you'll have a better shot at launching well and reduce some wheel hopping.
