Tom, not only is the consensus reached here not worth anything, but I would say we are not at a consensus of any kind.
I have real problems with the notion of other rules sets being used to define our own. A couple of things to consider:
First, the ITAC has utterly no control over Prod, GT, SS and so on. If they make a change to their rules it can not/should not effect the legality of an IT car. In this case, using Joe's logic if prod and GT removed the specific reference to QR hubs that would suddenly change IT. It can be difficult enough when the ITAC can only advise the CRB on IT issues, why open the door to the reasoning that a decision in another class changes to legality in our own?
Second, there is no guarantee that the different groups (prod, gt, it and so on) ever looked at each others rule on a given matter before putting pen to paper. The logic of saying that if IT had intended QR hubs than they would have written it the way prod does if flawed. By trying and interpret a rule in IT based of another class is trying to read intent into the rule. What if the ITAC is the first to write a rule and when prod writes something similar the wording is different? Should that change the legality in IT?
Finally to Greg, while I can understand your frustration I don't think running a competitive T3 or T4 is going realistically be cheaper than a competive ITA car. And then you have to factor in the car of the month consideration in Touring where IT tends to be much more stable. Just take a deep breath, step away from the keyboard and maybe you'll remember why this is supposed to be fun.
