Most tracks run a pro and sportsman class and many in the sportsman have been doing this a while in our region, have top-notch equipment but are not sponsored in any form so they are eligible for Sportsman. Most run 2 classes Sportsman and Pro. At our local track we just run 1 class and everybody together. Pros show up and they are usually the fastest guys. Then your top Sportsman usually make the amain a handful of us so it sorts itself out.
But for bigger points series what criteria would you use to determine if a racer should race Sportsman or Pro? If you are finishing top 3 in club races with 20+ sportsman buggy's and win a few, but have not won any big races does that qualify for a bump to pro?
