Race fans who watched the Consumers Energy race on Sunday saw a NASCAR official check the lug nuts on the tires of race winner Kevin Harvick’s car to ensure that all 20 of them were properly secured.

The wheels on Harvick’s car were properly secured and free of penalty; but not all of the teams were so lucky.

During the post race inspection process after the Firekeepers Casino 400 on Saturday, NASCAR found that the number eleven Joe Gibbs Racing car driven by Denny Hamlin had one lug nut improperly secured.  As a result of the infraction, number eleven car crew chief Chris Gabehart was fine $10,000.

After the Consumers Energy 400 race at Michigan on Sunday, NASCAR determined that the Hendrick Motorsports number 24 car driven by William Byron was also found to have a single lug nut improperly secured; crew chief Chad Knaus was fined $10,000 for the infraction.

In other penalty news, NASCAR issued no further penalties to Roush Fenway Racing.  Prior to the race on Saturday, NASCAR confiscated the spoilers from the RFR number six car driven by Ryan Newman and the number 17 driven by Chris Buescher.  NASCAR also docked Roush Fenway 20 owner and driver points for both teams and fined the teams $25,000 each.

Prior to the Gander RV and Outdoors Truck Series race on Friday, NASCAR penalized the number 13 ThorSport truck for an infraction involving unapproved parts on the truck bed side panels.  The number 13 team was docked 10 car owner and driver points.  No further penalties were levied.
