Kirk, I'm with you. And on your last point, the entire aspect of stability is what I think both you and I hear as the "big thing" (along with the not too much, not too little ruleset) that attracts and keeps drivers and owners to IT.

And for that reason, I think allowing dual classification (as in the case of the E36 in ITR and ITS) is warrented when there are material changes that need to be made to the car to switch classes.

This car is a good example, and if I were king, my policy would be to extend 3 years "granfathering" of dual classification for any car that got moved across the ITB/ITA line, or the ITS/ITR line. Of course, I'm not talking about taking your ITA wheels and running ITB. You want your 7"-ers? Run in ITA. You want to be in ITB? Get the rims.
