I agree and disagree with you on a lot of things. I don't think you should set up a car without a body. I understand that a body isn't going to make up for a poor handling car, but like any other tuning option, it is a variable to deal with. The way I think about it is this: It is a tweaking tool like anything else and must be incorporated in to the setup initially. To me its like tuning without camber or without changing springs. Sure you can get close, but like anything, you can't change something without affecting something else. I feel you have to treat it like a whole package. If are car already has a lot of turn in, then the body might make it have too much. Bodies have certain characterisitics that can't be overlooked or accounted for. I do agree that people do jump on the bandwagon and follow blindly, but that's always going to happen by people either too lazy, short on time or uneducated to figure it out themselves. The Stratus works for some people, that's why they use it; it isn't because its the best looking or most exotic. Come on, a Dodge Stratus; probably one of the boringest cars on the road. Anyway, my point is the body is a tuning aid, not a fixer. I believe just about any of these bodies could be made to work, but only in conjuction with the car. If the body pushes, then you compensate by tweaking in other areas to make it push less.
Also, about ROAR rules, since I don't have alot of time to tweak, I prefer to elimiinate another variable. A lot of the races I do are ROAR sanctioned or they foillow their rules, so I don't want to have to go back and forth betweeen legal, and illegal bodies. There are actually a lot of bodies that work that aren't legal. The illegal HPI body I'm posting here has tons of downforce, but to tweak my car to this body is something I don't want to have to go through too. Anyway, I've rambled enough.
