The rules of racing have a lot of grey areas that they leave untouched. I don't enter these areas as winning isn't that important to me but stand at the starting line and listen, and I mean listen to cars leaving the starting line. There are ways to modify ignitions to act as traction control, slew boxes, and I'm sure everyone has heard about "the dirty dozen". I know I have as I raced against some of them. Don't be blind and think cheating isn't going on.
