For what it's worth, IRDC will once again be hosting the "German Touring Car Challenge" special race, I believe at the July 30/31 race weekend at Pacific Raceways. It seemed to me like the 44 Cup guys enjoyed themselves in this particular race.
The success and popularity of this special race was noticed by some of the other clubs in Conference, and it's my understanding that they are considering or working on their holding their own special race group that may be quite similar.
On this theme, there has been talk of possibly trying to put together a "German Touring Car Challenge" series, where an informal championship of sorts could be earned. It wouldn't be an officially sanctioned class or series, just an opportunity to build some buzz around a cool concept. Maybe something like having a GTCC special race at each of the circuits that Conference visits this season; Portland, Seattle, Mission, Grass Valley and Spokane. A 5 race "series", where the total points determines the Conference GTCC "Champ".
It should be as simple as having someone take the lead to contact the race chairs at each club to test the concept, and figure out a common simple rule set.
