Grand Am and NASCAR have announced that the Rolex Series and the Sprint Cup will run on the same day for the July 4 meeting at Daytona.

The Brumos Porsche 250 will take the green flag that Saturday afternoon, followed by the Coke Zero 400 Powered By Coca-Cola at 8 pm.

Previously, the Brumos Porsche 250 was held on the Thursday evening ahead of the weekend. It will remain a one-day event, with practice and qualifying Saturday morning.

"This is a tremendous opportunity to showcase our exciting style of racing in front of more than 100,000 fans," Grand Am president Roger Edmondson said. "Coming off the photo finish of last year's race, along with the exciting conclusion of the recent Rolex 24, non-traditional sports car fans will experience a terrific show."

The heritage of the Brumos Porsche 250 dates to 1967-1983, when it started at the stroke of midnight on July 4, followed on the morning of July 4 by the NASCAR Sprint Cup Series race then known as the Firecracker 400. Grand-Am revived the event on the Thursday date as part of its inaugural 2000 season.
