NASCAR's season-ending championship race has sold out all of its grandstand seats.

Homestead-Miami Speedway President Matthew Becherer says all premium seating has also been sold out for Sunday's finale.

Denny Hamlin, Kevin Harvick, Joey Logano and Ryan Newman are the four drivers racing for the Sprint Cup championship. The title will go to the highest-finishing driver.

Tickets remain available for the Truck Series finale on Friday night and the Nationwide Series finale on Saturday.

Phoenix International Raceway sold all of its seating for last week's race. The championship field was set at Phoenix, and tickets for that event were gone a week in advance.
