It was a Busch race, which is why Stewart, Gordon, Earnhardt, etc. weren't running.

The ringers like Boris Said and Ron Fellows have their hands full when they go up against the Nextel guys, which happens twice a year and Jeff Gordon is as good of road racer as anybody. Earnhardt ran the Rolex24 in a C5R with his dad a few years ago.

It's not that they "can't" make right turns, it's just not their main venue.
