Right Kirk, go back and look who has been arguing for the best of IT all along in this discussion vs. who has been trying to selfishly protect the use of their existing 6" wheels.
Also, go back and look. I have NEVER once argued about a competitive advantage. I have argued the greater availability of 7" rims at a lower price, reduced tire wear (cost) due to better sidewall angles, and the side benefit of ease of moving between classes.
You are right, what is best for the future of IT is what should be considered here. Yes, rules stability is important. But we also must change w/ the times. The choice to use those 6" rims is based on a historical reason that is no longer applicable. And the greater availability of suitable rims in the 7" size, at a lower cost, is good for the future of IT.
In fact, this is very similar to the 15" rule change that was lobbied for heavily by *you* 4 years ago, despite the fact that it was against rule stability. Why? Because it was a change that was good for IT. Change can be a good thing.
15" diameter change discussion (note Kirks agreement w/ my point about the side benefit of easier class changes):

Well done, Scot. I always appreciate when someone does their homework.
Where I'm internally inconsistent, I believe it's because I can see multiple sides of an issue. In THIS conversation, I argued my own interests rhetorically in an effort to illustrate that others are doing the same thing. Yeah, I have an interest - an investment - there but that's not the entire issue.
Point being (yet again) that if I want one thing, and you want another, the ITAC has the unenviable job of doing what is right for the long-term health of the category. They are left to decide which is the lesser of two evils - leaving the wheel solution options tight for some drivers, or making fundamental changes to the rules category:
** Different widths for different models in the same class
** Wider wheels for entire categories
** Weight penalty plus wheels for anyone who chooses
** Etc.
Up sides and down sides. I FIRMLY believe that in this case, any of the options presented is a problem. Anything that promotes differences within categories (the first and third choices above) is particularly bad so of those, a shift to bigger wheels all around is the least awful.
On the 15" issue, *I* argued (and still believe) that that particular change didn't have the down sides to keep it from being a good way to help resolve the wheel availability issue (which I've never denied exists). It's very difficult for me to conceive of a way that an ITA guy who goes from a 14x7 wheel to a 15x7 wheel is going to automagically inherit a relative competitive advantage. Wheel/tire rotational inertia is higher, tires of the same OD are more expensive, and it takes the gearing the wrong way. On the plus side, some may like the increased sidewall stiffness. It's a wash.
That is not the case - to my mind - of allowing another inch of width. And I'm NOT going to endorse differential specifications for cars within a category - spec line allowances, etc. - because despite anyone "rejecting" it, I KNOW FIRST HAND what those damned camels will do to a perfectly good rule set.
And finally - and read this carefully, Scot - you are either being disingenuous or just not thinking about your own case critically, if you don't recognize that all of your arguments are about your own competitive advantage.

You are talking about saving money one wheels (so you can spend it elsewhere going faster), and saving money on tires (so you can buy more and run them in newer, faster condition more often. It's handy that you can make this case for the Fiero in the context of cars getting moved but do this test - would you endorse the idea of wider wheels being allowed on cars moved from A to B, if the rule included a clause restating the philosophy that "it is contrary to the first principles of IT and the wishes of the founding fathers, so cars currently in B will NEVER EVER, EVER BE ALLOWED TO RUN 7" WHEELS." Ever?
Say "yes."
I have never been about preserving the rules for rules' sake. I am - despite my best efforts, sometimes - adamantly against rules creep and competition adjustments, defined in the subtle and complex ways that I spent more than a quarter freakin' century learning to define them. And I get very worried when people won't even consider that their own competitive hopes and desires can't be put ahead of the big picture.

PS - as a footnote, I don't think I WOULD realize any significant performance advantage on my car, with 7" wheels. We've just gone to a 225 front, 205 rear package, supporting my belief that it is very possible to go too wide. And BTW, 14x7's are less available than 14x6's -
that was the poster child for the +1" diameter case, meaning that I'd be facing, along with a lot of others, the question of going to a 15x7...
