I have to agree if the 99 is out of the picture. Cross classing with seperate prep starts down a bad road. The rear dif is a wash but it has been an understood point that we ignore it. I have much less of a problem with letting it slide at races than writing it into the rules and starting a bad precedent. Has there ever been a protest of a SM running in ITA getting bumped for a diff? Let it Gooooooooo.
