NASCAR inspectors cracked down on splitters Friday at Dover International Speedway and it left Monster Energy NASCAR Cup Series teams scrambling to get on track for practice.
Officials were looking to ensure teams had a flat splitter on the front of their vehicles. But the thorough process resulted in teams being stuck in the inspection line as practice began. Only half of the field had made it on track by the time the session (which was 50-minutes in length) was 30 minutes old. All cars did get on track before the session’s conclusion.
Paul Menard was fastest at 159.830mph. Defending race winner Jimmie Johnson jumped to second fastest late with a lap of 159.440mph. Kevin Harvick was third fastest at 159.412mph with Kyle Busch fourth fastest at 159.299mph. Brad Keselowski completed the top five at 159.208mph.
The rest of the top was Martin Truex Jr. at 159.081mph, Kyle Larson at 158.990mph, Ryan Blaney at 158.919mph, Clint Bowyer at 158.884mph, Ricky Stenhouse Jr. at 158.723mph.
Joey Logano, 12th fastest, clicked off the most laps in the session at 23.
