Dave,

wasn't there a thread here or on the sandbox that mentioned some ITB cars came new with 6.5" rims? i think maybe the current generation VW bug?

my take on that is allow them 6.5" rims if they run the OEM rim. otherwise they run 6",

it strikes me as a bit absurd that one cannot use the OEM rims for a somewhat entry level race series. for my honda and maybe yours, going to the 6" rim was 20% wider than OEM, not ~10% narrower.

but the tire & rims of current production are much different than that of 25-30 years ago. Tim Suddard mentions this a bit sort of in this month's GRM.

i think the club needs to go this way and i would give some latitude to the ITAC on this as long as they can back it up with a reasonable rationale. otherwise, we are going to have to consider something akin to NASA's PT where you can go to x" rims with a weight increase of xy pounds. then we pick our poison and live with it.
