What's required to qualify for nationals? No one runs GTS in NorCal probably because most of us run with PRC and have great Porsche only races. However, it wouldn't be too hard to run a couple non-PRC races (in addition to the PRC ones!) to qualify. There isn't a lot of incentive to do that now as it means a looong tow to Ohio or arranged transport and a flight.
