NASCAR is performing a deeper inspection process after the 2026 Southern 500 at Darlington Raceway this weekend. Corey Heim's No. 67 car for 23XI Racing has been taken to the NASCAR R&D Center for further inspection after Darlington, the sport announced. Heim finished in 19th place on Sunday night.
The 23XI Racing driver had a tough night after a pit-road penalty and being trapped one lap down for a period of time. NASCAR taking Heim's No. 67 car to the R&D Center doesn't automatically mean something is wrong; however, it does heighten the risk of a potential penalty.
In the NextGen car era, drivers and teams have received significant penalties when NASCAR takes a car to the R&D Center. There have been several occasions when they have lost over
100 points due to an infraction. Most cars are cleared after going to the R&D Center, but exceptions exist.
Heim will likely be OK; however, NASCAR has blasted teams in the past for any wrongdoing.
