This season NASCAR has moved the post race inspections from their R&D center in the middle of the week,to the tracks themselves after each race.

Race winner Brad Keselowski’s car passed inspection, but there were teams who were not so lucky.

Three teams – two from the Monster Energy Cup Series and one from the Gander Outdoors Truck Series – were caught with lug nut infractions after the race at Atlanta Motor Speedway.

The number 95 Leavine Family Racing car driven by Matt DiBenedetto, the number 43 Richard Petty Motorsports car driven by Bubba Wallace, and the number 13 ThorSport truck driven by Johnny Sauter were all found to have one lug nut unsecured in post race inspection.

As a result of the infractions, the number 95 crew chief Michael Wheeler and the number 43 crew chief Derek Stamets were both fined $10,000 each. The number 13 truck crew chief Joe Shear Jr was fined $2,500.

Originally NASCAR had stated that the number 13 Germain Racing car driven by Ty Dillon had also been charged with having an unsecured lug nut.NASCAR later noted that the charge was in error due to a miscommunication.
