Removal of the tires leads me to believe they're gonna have more and more go cart races. I think this years go cart races are just a trial. I think next year they'll be a full blown go cart track. They'll get more go carts than they get in any division they currently run.
It's not about them saving you axles or race cars....it's about them making money! Hopefully I'm wrong...been wrong a lot before, it's just what I see on the horizon.
Time will tell I guess?
