What some of the Chase contenders are driving this weekend.....
#2-Brad Keselowski: The No. 2 Miller Lite Dodge Charger team will race chassis PRS-813 during Sunday's AAA 400 at Dover International Speedway (DIS). Keselowski last raced this chassis to a fourth-place finish at Pocono Raceway last month.
It has been updated to the current Penske Racing specification.
#5-Kasey Kahne: Crew chief Kenny Francis has selected Hendrick Motorsports Chassis No. 5-717 for Sunday's race at Dover. Kahne has raced this car to three top-10 finishes in three starts this season, including an eighth-place result in April at Kansas Speedway, a track in the Chase.
#14-Tony Stewart: Chassis No. 14-708: This car debuted in May in the Southern 500 at Darlington (S.C) Raceway where Stewart rallied Chassis No. 14-708 from its 17th-place starting spot to finish third. Its second start came in June at Dover (Del.) International Speedway. It endured a much different outing, qualifying 29th and finishing 25th, 69 laps down after getting caught up in a 12-car accident on lap 10 of the 400-lap race around the 1-mile, concrete oval. With new sheet metal all around, Chassis No. 14-708 returned to the concrete for its third career start in August for the night race at Bristol (Tenn.) Motor Speedway. There, the car rallied from being a lap down in 34th place early in the race to vying for the lead with Matt Kenseth on lap 333. Stewart and Kenseth banged fenders and crashed, whereupon Stewart threw his helmet with pinpoint accuracy at Kenseth's car. The resulting 27th-place finish was at least offset by the "10" Stewart received from the Bristol crowd. Chassis No. 14-708 will make its fourth career start and second at Dover in the AAA 400 on Sunday.
#15-Clint Bowyer: Primary chassis No. 733 finished sixth a Pocono in June and eighth at Pocono in August in its only racing action this season. Backup chassis No. 716 finished sixth at Las Vegas and also ran at Kansas, Kentucky and Indy.
#16-Greg Biffle: Primary: RK-809 Last ran Michigan - finished 4th; Backup: RK-803 Last ran Pocono - finished 15th
#17-Matt Kenseth: Primary: RK-802 (Last run at Bristol)
#29-Kevin Harvick: will pilot Chassis No.383 from the Richard Childress Racing NASCAR Sprint Cup Series stable in this weekend's AAA 400. Harvick raced this chassis at Phoenix International Raceway in March and Dover International Speedway in June, collecting second-place finishes in both events. Most recently, the Bakersfield, Calif., native drove this Chevrolet to a 15th-place finish at Bristol Motor Speedway in August.
#48-Jimmie Johnson:: Chassis No. 728 serves as the primary for Johnson at Dover. Chassis No. 681 serves as the backup.
#88-Dale Earnhardt, Jr.: Crew chief Steve Letarte and the No. 88 team will unload Hendrick Motorsports Chassis No. 88-745 this weekend at Dover. Earnhardt first raced this chassis to a 12th-place finish at Bristol (Tenn.) Motor Speedway in August.
