No rules besides running the tire. Partly in an effort to contain cost. That cost containment means you have to get a big 410, new wheels, new tires, and all super light weight everything to try to be competitive. Should only cost the top teams $60,000 in "savings" to run up front next year. The guys that are going to run current SOD cars are just going to go backwards. Sure glad I live 5 hours away from any car similar to mine for next year, and right in the heart of the SOD tracks.

The quickest and easiest way to cut weight is the safety stuff. 3 layer suits are heavy, hans, full containment seats, arm restraints, steel heims and steering componenets, etc.

Maybe someone will save 360 racing in Michigan. I need a beer.
