Thanks, Rodger - that's helpful information.

Wait a second. I sympathize with your need to purchase new rims however that statement a bit funny to me. First, you're being moved from a class where the car in a competitive field has absolutely no shot at winning. Now you're moved to a class where you're in a MUCH better position even with those wheels and weight. You also need to keep in mind that you are choosing not to purchase rims. It would be similar to me complaining that almost everything with my car had to be custom built. I can either choose to use the original equipment (Shelby = 6" rims, right?) or spend the money on other better options.DaveOther cars in ITB are receiving an advantage now as I am runing 20# wheels and more than 50#over weight.
During the ITB impound I pointed out to Jake the Sabb and implications of using fender width to determine maximum wheel sizes. The front fenders (the rear were tweeked a bit) could easily be an additional 3" inches wider than it was. Using the chalk method and with decent tire pressures, I wouldn't be totally surprised if it were an additional 5"s. (It has Hoosier 225s) I also looked a Volvo, plenty of room there too.

Dave, I don't doubt what you say about being able to stuff (6 + 3) 9" wide rims under the Saab. Maybe 11", but I don't thin there is a great supply out ther of those wheel and even then a tire would be a problem. Same with th Volvo. Given the tire sizes run, 7 or 8 is probably optimum.
fitment still better. Maybe a tweak would be all rims the same size. Dos that help anybody?

cut the crap!
There are a few circle track wheel manufactures that would be happy to supply those rims. I sure would give them a try at handling tracks such as Lime Rock Park.
I guess my point is that other than a temporary dual classification, I'm not sure there's an easy answer that will make everyone happy.

I would like to know of some supplier. All I have found is spinwerks. They have only 4 rims in 6" and are not going to carry any more. $231/each = ouch!

Is making everyone happy a requirement? or is what is best overall, Maybe 7 in ITB is not the best answer, If there were a good supply of 6" under 15# in every bolt pattern in ITB, there would be no issue at all.
I still think fitment is the best over all answer.

I agree that the price sounds expensive for an off-the-shelf 14x6 wheel, but ... still, the price of a couple of sets of those (especially when you consider that you can sell your 7" wheels for SOMETHING) is MUCH MUCH MUCH less than it would have cost you to try to be competitive in ITA. If you are overweight for B, you must have been really really overweight for A!

What about the idea of you can run the stock wheels that came on your car or being your car came on stock or run an aftermarket wheel up to a width of 6".
That should cover everyone. another option is instead of buyring 230 per wheel.. it would be cheaper to machine weight out of your stock wheels. Even if yo uhad to buy a student version of solidworks to test it.

...unless the car originally came with 6" wheels, stock. In that case you're in the "let them eat cake" scenario, same as, for example, a car that's coming in new (not a move) and doesn't have as many wheel options as the current competitors do.
Look, this whole idea of "stock wheels" is a slightly misplaced in context, at least in terms of historical significance. The original intent of the width rules was to minimize expense and maximize parity by setting an outer width limit, loosely based on what was the largest-width available for the cars in that class at the time. In other words, you couldn't have parity by making people stick to stock widths because some came with 5" wheels and some came with 6" wheels, so since many cars came with 6" wheel widths you open it up to 6" wheels for everyone. "Back then" 6"-wide wheels were the shits for cars in this class! Today, not so much the case.
So, if you want to stick to the original intent of the rule, you need to do a survey of all stock wheel widths in the class and find out the largest-stock one and go with that for everyone.
An alternative is what I described prior: ignore what's stock and go with what's best in terms of availability and price to cover the field effectively. That may or may not be coincidental with the suggestion above.
Or, you can just stay pat, and the current ITB and ITC drivers are happy, while others coming in are possibly unhappy (but this doesn't sound like a significant factor among this group). - GA
I have another cheap Idea.. buy a set of cheap 14x6 wheels and get them re-drilled.. That is significatnly cheaper than $230 per wheel. This is a cheap expense.. would the OP rather run his car on 7" wheels, that he honestly did not have a chance of a podium finish with a decent field? I know that I personally was excited of the fact that my car was moved to a class where it can be comeptitive.. (ITB MR2) I purchased it as old A car. I told the seller to keep his 15x7" wheels it came with to lower the price of the car to help pay for the 14x6" wheels I had to purchase to make it legal.
I can see where the OP is coming from.. his car was re-classed and now he has to buy new wheels to run legally. I was in the same boat with the car I bought.. so I had to get rid of the wheels and buy a set of 6" wheels. That would kinda erk me if all along a few months ago I could of just kept what what the car came with.
