HAMPTON, Ga. — Kyle Busch’s race-winning entry in Saturday’s Rinnai 250 NASCAR XFINITY Series race failed post-race inspection for a height violation, according to NASCAR officials.
Busch’s car measured too low on both the right and left front.
The winning car, as well as the No. 1 JR Motorsports Chevrolet of fifth-place Elliott Sadler, which was the random car, will be taken back to the NASCAR Research & Development Center in Concord, North Carolina, for final inspection.
“I don’t know. I didn’t feel anything happen … over the course of the day,” Busch said after joining Camping World Truck Series race winner Christopher Bell in the media center afterward. Bell competes for Busch’s Kyle Busch Motorsports organization.

“I don’t remember what kind of adjustments we were making; I know we were going track bar down and wedge out so that should actually kind of lifted the front a little bit maybe, but I don’t know how low it was or anything like that,” Busch said. “I haven’t heard anything. I don’t even know what the penalty is now.”
Busch said the No. 18 entry is scheduled to run the entire XFINITY schedule with a variety of drivers, “so I guess I’ll have to figure out who I’m working with next week.”
He is scheduled to compete in 10 of this year’s XFINITY races, including next week when the series travels to Las Vegas Motor Speedway for the Boyd Gaming 300 on March 11.
Busch led twice for 26 laps in the 163-lap event, the second stop for XFINITY Series teams this season, but beat the field off pit road late for the final lead change of the race. He led the final 19 laps.
The win was his 87th in the XFINITY Series and the 171st overall among NASCAR’s three national series (Monster Energy NASCAR Cup, XFINITY and Camping World Truck).
Any penalty or penalties as a result of the infraction are expected to be announced mid-week.
