My track has decided to do a 17.5 independent class and a 17.5 sponsored class. If your motor is over 100 bucks pr your sponsored you run sponsored class. If you don’t have either you run independent. This has helped me worlds and I do t see how anyone would be bothered by it u less it creates less people for them to sandbag against. For me being new it was discouraging knowing the three same guys are on top week after week. Now I feel like it’s anyones race in my group and I’m happy with the rule change. Lot of guys like me don’t have thousands to invest In the hobby month after month
