IN rally cross tire choice can make your class different. In Club Rally they don't make classes change cause everyone runs them regaurdless depending on terrain. So in Club Rally he probably is in the lower "stock" class. But in Rally Cross he's bumped to run with the open/preparred class.

After reading thru the class rules, he would be in Rally Street Front-Wheel Drive. One step up from stock but not in prepared. I forgot that tires are free in rally street classes.

BTW, cages are allowed (and even encouraged) in street stock classes. You can even have race seats bolted in with harnesses. It's performance advantages that bump you up in classes, tires being one of those.
