The crew of Kyle Busch’s No. 18 Toyota found a cracked track bar mount on the car before the race and changed the part, preventing what could have been a serious failure at speed.
Crews checked the other Joe Gibbs Racing cars and determined that the issue on the No. 18 was isolated.
Busch posted the fastest lap in Friday’s final practice session, but he was more concerned with longer runs.
“It’s nice to have the fastest lap, but it doesn’t really mean much,” Busch said. “What we’re really looking at are lap averages – but it’s a good car.”
