This chassis made its last appearance at Dover International Speedway in June, when Busch picked up the ninth starting spot but had his day end prematurely due to an engine failure. It’s also the same car the team used at Darlington Raceway in May, when Busch competed in the top-10 during the majority of the event before settling for a 21st place finish due to a late-race spin. Prior to the 2012 season, the car was used as a roadcourse car. Hendrick Motorsports built this chassis with a universal clip, which allows for greater adjustments with the geometric points on the chassis. As such, the team converted the car from a road-course car to an intermediate-track car for this season.
#99- Carl Edwards - The No. 99 will carry the Subway paint scheme at Atlanta this weekend. The crew will unload RK-782 which last ran at MIS in June where Edwards finished 11th, and also ran the All Star race and California.
