JOLIET, Ill. — Kyle Busch‘s most recent NASCAR XFINITY Series victory came with a slightly sour post-race taste Saturday at Chicagoland Speedway after the winning car was found to be too low in a post-race technical inspection.
A NASCAR spokesman said that the Joe Gibbs Racing No. 54 Toyota failed to meet the minimum height requirement on all four corners of the car. Any potential penalties would be determined after further inspection of the car early next week at the NASCAR Research & Development Center in Concord, North Carolina.
In the past, such violations have warranted P2-level violations according to the NASCAR deterrence system that was introduced before the 2014 season.
Busch led 102 of 200 laps in Saturday’s Furious 7 300 to notch his fourth XFINITY victory of the season and the series-leading 74th of his career.
