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 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!

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.[/quote]
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.
