So, you're thinking about cheating and then you post the thought on a public forum...
Here in SoCal a guy in a FS Mustang did just that a few years ago. His competitors got suspicious when he suddenly knocked two seconds off his best time from one event to the next. That night they went to the StangNet forum and found his post.
At the next event, they had made copies of his post and handed it to all his competitors in FS and dozens of other people. After about a dozen competitors made it a point to walk up to this cheater and hold the post up to his face he left and has never come back.
In any competition, your peers will do a very effective job policing the sport.
