NASCAR: No. 00 Custer car found to be illegal at Michigan

Stewart-Haas Racing’s No. 00 Ford Mustang was found to have an illegal front splitter in pre-race inspection at Michigan last weekend.

As a result Crew chief Jonathan Toney was fined $25,000 and the team, along with driver Cole Custer, were docked 20 owners and drivers points, respectively. Five playoff points will also be deducted from their postseason totals.

Officials cited Sections 14.4.3.C&H in the NASCAR Xfinity Series Rule Book. Section C states that “except as specified, splitters must be used exactly as supplied from the manufacturer,” with requirements and reference dimensions provided in an attached drawing.

Section H states that “rounding of any edges of the splitter will not be permitted.”
