Erstwhile championship contender Dillon Battistini, who enters the race in fifth place in points after a series-high four wins, left Panther Racing after Infineon and signed a one-race deal to drive the #22 car for Team Moore Racing.

“I'm thankful for opportunity to drive for Team Moore Racing this weekend, and hope to be able to rack up my fifth win of the season," the Briton commented, "I'm glad I am able to explore my options for next year and gain experience with working with a new team.”

With Team E not running at Chicago, Milwaukee race winner Bobby Wilson joined Panther Racing to take over Battistini's seat.

“The #15 car has high expectations," he admitted, "It's definitely capable of being in the Winner's Circle every time on an oval, and that's where I expect to put it for the National Guard and Panther. It's different working with a new group of guys, but they have been really nice and helpful - it makes the adjustment easier. It will help when I can get all the names and faces put together, but I think that it will be a successful weekend.”

Other changes include Pablo Donoso making his second start in the #3 Mo's Gold entry and 2005 series champion Wade Cunningham returning to drive the #9 Integra Motorsports entry. Battistini placed seventh in his new mount, five places ahead of his old car, with Cunningham one further back, in 13th.
