Darlington Raceway is also known as “the track too tough to tame” because it is rough on tires and can be very difficult to run.

This past weekend’s triple header was also hard on pit crews and lug nuts.  Several teams were issued penalties relating to unsecured lug nuts with two of those penalties resulting in a suspension.

NASCAR officials determined that the number 14 Stewart-Haas car driven by Clint Bowyer and the number 18 Joe Gibbs Racing car driven by Kyle Busch had two lug nuts improperly secured during the post race inspection process.  As a result of the infractions Bowyer’s crew chief Johnny Klausmeier and Busch’s crew chief Adam Stevens were fined $20,000 each and suspended for the race at Richmond this weekend. 

The race winning Stewart-Haas Racing number four car driven by Kevin Harvick and the Hendrick Motorsports number 24 car driven by William Byron were found to have a single lug nut improperly secured during inspection.  The crew chief’s for each team have been fined $10,000 each.

No further penalties were assessed the Penske Racing number 12 driven by Ryan Blaney other than those issued prior to the race on Sunday.  After a five pound bag of ballast was found in Blaney’s car during pre-race inspection, NASCAR docked team owner Roger Penske and driver Ryan Blaney 10 points, the crew chief was ejected from the track, and Blaney had to start the race from the back of the field instead of his number seven starting spot.

In the Gander RV and Outdoors Truck Series, the Bill McAnally Racing number 19 driven by Derek Kraus was found to have a single lug nut improperly secured.  As a result, crew chief Kevin Bellicourt was fined $2,500.
