I think a true STOCK class is needed]
Every track I have bewen at does have a stock class. What needs to happen is the track owner or someone delegated to force people that dominate the stock class to move up to a expert stock class. If your running the same lap times as people in expert stock its time to move up! People stay in these classes because they win constantly and this discourages new people to stay in the hobby.
Our local track offers a rookie class, stock class, and expert stock. There re people who drive nothing but rookie. Thats just wrong. You win like 3 rookie races and you should be forced to stock class. There are people that go to large off road races and sit in the rookie classes. Once you enter a large race as a rookie you in my opinion are no longer a rookie.
