NASCAR has fined three Joe Gibbs Racing crew chiefs and suspended three JGR car chiefs for one race for non-conforming front splitters confiscated during prerace technical inspection Sunday at Michigan International Speedway.
It fined JGR crew chiefs Adam Stevens (Busch), Mike Wheeler (Hamlin) and Chris Gayle (Jones) $25,000 each and suspended the car chiefs (Jason Overstreet, Nate Bellows and Brandon Griffeth) for those drivers for the upcoming Cup race at Sonoma.
A JGR spokesman said the team will not appeal the penalty.
The penalties continue a NASCAR trend toward suspending car chiefs, who often play a more hands-on role with the car than the crew chief during a weekend. The car chief typically is in charge of setting up the car to the specifications decided by the crew chief and engineer.
NASCAR has intensified inspection of the front splitters – a key component in impacting downforce as well as how the air flows around the car — in the last five weeks to make sure they are flat.
