Illegal is illegal--period. No gray area there unless you choose to ignore it. I'm a Mazda man but this is a total crock to invent more places to run the same friggin car 50 times a weekend. We already get the shaft with run groups because of them as it is. Lets just make a Miata legal for every class and screw with the weight until it fits everywhere. I bought one for my wife and already hate the friggin thing before it even runs now.
