Michigan International Speedway bore a striking resemblance to a superspeedway last weekend when two race cars went for dramatic tumbles on the backstretch, including the NASCAR Chevy Camaro of Corey LaJoie in the Cup Series race and the No. 28 NASCAR Ford Mustang Dark Horse of Kyle Sieg in the Xfinity Series. The sanctioning body has now announced new regulations for the Cup Series cars that will hopefully keep them planted on all fours should a similar crash occur at Daytona.
A report from NASCAR.com details the changes headed for the NASCAR Chevy Camaro ZL1, Ford Mustang Dark Horse, and Toyota TRD Camry race cars. Wind tunnel tests were performed this week after LaJoie’s flip, prompting NASCAR to mandate a new right-side air deflector, which will be required as of this weekend’s race at Daytona on August 24th, 2024.
The new component will increase the liftoff speed of the race cars as soon as a spin starts, making the vehicle less likely to go airborne in the event of a wreck. NASCAR will supply the part to teams, and it matches the air deflectors already mandated for the left sides of the race cars.
The mandate is a direct result of LaJoie’s wreck at Michigan. His race car went sideways and almost immediately blew over, flipping onto its roof before rolling back over. Interestingly, the roof flaps atop the No. 7 Camaro did little to slow it as it spun out, causing it to flip like it weighed nothing. LaJoie was unhurt in the crash and was able to exit the race car under his own power after it came to rest in the infield grass.
At this time, NASCAR has not announced changes to the Xfinity Series cars in response to the incident involving the No. 28 Mustang of Sieg.
The Cup Series race at Daytona is scheduled for 7:30 p.m. ET on Saturday night.

Use to think this was a great website but can’t deal with the ads anymore. Can’t even get rid of them.
This really sucks.
you talking bout the ads you see on the youtube link? That is not this site doing that. The only ads I see is the one for “Win 2 supercharged Cadillacs”.. Get yourself a good ad blocker extension for your browser. There is a good one that starts with a “U”, but I dont want to say name of it on here.
Galen Issac. Thank u for the heads up. I will look in it. Have always enjoyed GMA and look forward to receiving it every day.
