Overview

• Michael McDowell’s No. 71 and Shane van Gisbergen’s No. 88 were cited for unapproved front splitter adjustments discovered between inspection passes at Kansas Speedway.
• Both teams lost pit‑stall selection, must start at the rear, and will serve a stop‑and‑go penalty at the green in Sunday’s Hollywood Casino 400.
• Crew chiefs Travis Peterson (No. 71) and Stephen Doran (No. 88) were ejected for the weekend after the violations were confirmed.
• Spire named Matt McCall as interim crew chief for McDowell, and Trackhouse engineer Chaise Eliason will lead van Gisbergen’s effort.
• Cody Ware’s No. 51 failed inspection twice before passing on a third try, leading to car chief Dave Jones’ ejection and loss of pit selection, while all 12 playoff drivers cleared inspection.
