   The business of NASCAR racing is big business, really big business, as most fans realize.
   And the business isn't doing quite as well these days as it once was….given the sagging U.S. economy and the impact of sponsorships on this sport.
   So it will be interesting to see just how CNBC does with Thursday night's hour-long (9 p.m.) NASCAR special: 'Inside Track: Refueling the business of NASCAR.'
   The producer is Darren Rovell: HERE.
