NASCAR handed down an L1-grade penalty Tuesday to the Chip Ganassi Racing No. 42 Chevrolet team of Kyle Larson for an improper rear window support discovered in post-race inspection after last weekend’s event at Kansas Speedway.

The No. 42 team was found in violation of Sections 20.4.h (vehicle body) and 20.4.8.1.b&c (rear window support and structure) in the 2018 NASCAR Rule Book, with the rear window not flush to the rear deck lid and the rear window support braces not keeping the rear window glass rigid in all directions.

As a result, No. 42 crew chief Chad Johnston was fined $50,000, and car chief David Bryant was suspended from the next two points-paying events on the Monster Energy NASCAR Cup Series schedule. Bryant will be available this weekend at Charlotte Motor Speedway for the non-points Monster Energy NASCAR All-Star Race.

Scott Miller, NASCAR Senior Vice President of Competition, told NASCAR.com the violation was similar to other technical infractions found earlier in the season. Those punishments included penalties for a bowed roof on the Las Vegas-winning No. 4 Ford of Kevin Harvick in March, a rear-window penalty to the No. 9 team after Texas in April, and last week’s sanctions to the No. 14 and No. 19 teams for similar unapproved bodies earlier this month at Dover.

“The industry has kind of seen a rash of this type of thing lately with the rear windows,” Miller said. “The teams have obviously found some performance in that area and they’re kind of pushing the envelope, not to say that anyone wants their stuff to come back looking like that and be illegal, but they’ve obviously found performance and they’re pushing the envelope, and when you do that, sometimes it pushes over the edge. I think that’s the case with this one and the case with the other ones we’ve had here recently with the rear window violations. It’s kind of more of the same.”

The penalty takes away the benefit of the playoff point Larson earned with his stage win at Kansas. The team was also docked 20 points from the drivers’ and car owners’ standings. The penalty drops Larson from 10th to 11th in the Monster Energy Series points.

Larson led a race-high 101 laps and finished fourth in Saturday’s KC Masterpiece 400 at the Kansas track, rallying after late-race contact with the No. 12 Ford of Ryan Blaney.

Chip Ganassi Racing issued a statement early Tuesday evening, saying that the organization would not appeal the penalty. “Although all parties agree that the infraction was unintentional and the result of contact, we will not appeal the penalty so that we can focus our energy on the All-Star Race and the Coca-Cola 600,” the statement read.

Miller, however, addressed that collision Tuesday, indicating that the No. 42 car’s body deformities were not completely the result of on-track contact.

“We don’t believe that was the entire cause,” Miller told NASCAR.com. “I mean, there’s a possibility that it could have exacerbated the situation a little bit, but we have evidence that shows that there were things happening before that contact.”

NASCAR also announced that the Team Penske No. 22 Ford team for driver Joey Logano was penalized for having one lug nut not safely and securely mounted in a post-race check. Competition officials issued a $10,000 fine to No. 22 crew chief Todd Gordon for the safety infraction.
