The IROC could not come up with a series sponsor. It has always had the money problems. I think Crown Royal was the last one. I always thought it was good racing because they looked like real production cars and not “make believes” that nascar runs now. Sounded better too.
I really do miss the IROC series. It always represented the best of the best, the champions of several series outside of NASCAR. I guess IROC auctioned off most of their assets after failing to get a sponsor last year.
One sponsor for 12 cars is spreading the money very thin.
