Do you recall what stadium truck racing is/was? Identical trucks raced by a field of enthusiasts. Well, now there is a similar race for celebs, called Superstar Racing Experience.

What if there was a racing series with big personalities that wasn’t stifled by corporate sponsorship with cars that were identically prepared to emphasize driving talent? 

It’s IROC basically, and Superstar Racing Experience is about fun, and that’s what co-founders Tony Stewart and Ray Evernham will deliver over the next six weeks. 

SRX essentially takes a dozen of the most iconic names in modern day motorsports and places them in identically prepared cars to race across six of the most venerable dirt tracks and pavement bullrings in the United States.

So, there will be a race Saturday night, from Connecticut, featuring Tony Stewart, Greg Biffle, Tony Kanaan, Marco Andretti, Paul Tracy, Willy T. Ribbs, Bill Elliott and reigning Indianapolis 500 winner Hélio Castroneves.
