I am not sure where you heard that about being loose with the rules, but I can definitely tell you it couldn't be farther from the truth.
Three reasons for that:
1) We all race together all year long, and would soon figure out if someone is cheating, or has added a cheater part.
2) We all race together all year long, and I personally would consider cheating a slap in the face from this group of people who are mostly friends.
3) This season at least there have been compliance checks after qualifying at the last 2 races. There was an "Impound all" and most, if not all cars are checked on a variety of things.
Hope this helps. Come join the fun! I will be missing the July race due to a torn-up car, but it is a good time.
