NASCAR fined the crew chiefs for two Cup Series teams and one Xfinity Series team for lug-nut violations that were discovered after the races last weekend at Auto Club Speedway.
Randall Burnett and Mike Shiplett each received a $10,000 fine when one lug nut was found to be not safe and secure on the No. 8 Richard Childress Racing Chevrolet and the No. 41 Stewart-Haas Racing Ford, respectively. Tyler Reddick drove the No. 8 to an 11th-place finish in Sunday’s Auto Club 400 while Cole Custer finished 18th in the No. 41.
