 Denny Hamlin , who won at Michigan International Speedway in the spring , was having a difficult time trying to improve the car handling of the race car he won with . Hamlin said , " It 's going all right . We were about like we were here in [ June ] as far as speed . We 're a little bit slow on speed as far as qualifying , but we feel like the race stuff is pretty competitive . " His teammate Kyle Busch was also struggling , adding , " Our [ car ] was loose off . We jumped back and forth in practice from tight to loose . We picked up from practice , but we couldn 't rotate the center like I wanted to . "
