Big picture...
I think ROAR is looking at the big picture.
If you force the really good guys (sponsored or not) out of stock, then he will stop practicing stock at his home track. He move up to the next class for the big races and his local club races too. (will not waste his time setting up a stock class car he can not run at the big events).
Which will open up the local track stock class for beginners.
Which will bring more new racers into hobby.
More racers = more money = more tracks!
