I think that I have been sympathetic to the plight of the RXs in ITA so give some thought to options that, if it does become necessary to create new classes, doesn't create one-marque classes.
I appreciate the allure of taking variations in cars out of driver competitiveness but the club just can't support a spec class for every make. We also limit the number of cars in any spec class by telling drivers interested in other makes that they can't play.
If IT2 siphoned off the too-fast FWD cars (Acura, Hondas, Nissans) wouldn't that return A to something like the status quo? There are other newer cars that are a better performance match to ITA-minus-Hondas-et-al, that should be allowed to play but the top end of the curve would go away.
Something to think about.
