A post-race inspection after Saturday’s NASCAR Nationwide Series race at Auto Club Speedway in Fontana, California found that the No. 39 team committed a rules violation.
NASCAR officials found that Ryan Sieg’s car exceeded the maximum rear body height requirement during post-race inspection (Section 20A-12.8.1C). The team was also found to have violated Section 12-1: actions detrimental to stock car racing.
