Sunday's Coca-Cola 600 was Humpy Wheeler's swan song at Lowe's Motor Speedway.
CONCORD, N.C. -- Crew chief Bootie Barker said he's been running all season the same wing mount setup on Scott Riggs
' car that was confiscated on Saturday after NASCAR officials decided it was illegal.
He reminded that the car passed two inspections on Thursday and wasn't impounded until somebody in the garage fingered Riggs' team and Haas CNC racing teammate Johnny Sauter
"I'm not going to make any excuses," Barker said before Sunday's Coca-Cola 600 at Lowe's Motor Speedway. "The car is my responsibility. But if you knew the whole story it would be like, 'Hmph.' I do myself more harm than good if I say anymore."
The cars were impounded prior to Saturday's Cup practice. Both teams were allowed to use backup cars and start in the back of the field.
Series director John Darby said NASCAR began looking into the allegations on Thursday night.
"All I know is the mounts were not in the same place as they were Thursday morning when they went through inspection," Darby said.
Darby said both teams are likely to face a punishment similar to what Dale Earnhardt Jr.
's team did last season after problems were discovered with the wing mount at Darlington.
Earnhardt was docked 100 championship points and crew chief Tony Eury Jr. fined $100,000 and suspended for six races.
"I don't know what the ruling will be, but it probably won't be good," Barker said.
Barker was concerned about the motive of the person that reported the alleged infraction.
"Some people recognized we were doing better and better in points and they would do anything they can to keep us off," he said.
Riggs was 26th in owner points, which is used to determine the top 35 guaranteed spots in the field each week. Sauter was 39th.
Barker believes he knows who turned the team in.
"I wish I could tell you some stuff," he said. "It would probably work against me until I know everything. The person I think that did it, and what we really did, it's pretty ... I've never done it. I'll put it that way."
France: New Car Takes Time
Despite complaints by drivers and crew chiefs, NASCAR chairman Brian France doesn't foresee any major changes in the new car until after the season.
"If there're changes, they're going to be tweaks," he said before Sunday's Coca-Cola 600 at Lowe's Motor Speedway. "They [teams] can't all figure it out if we're changing things as we go along. We've got to let them deal with the car they have. Some are figuring it out faster than others.
"We look at it every week. Obviously, the mile-and-a-half [tracks] have a slightly different show than anywhere else. But the car is really fine. It's doing absolutely what we want. We're satisfied with it."
