Indycar, F1, LeMans, and even local circuit Sprint Cars (on the rear axle) all race with 1 large center mounted lug nut.
NASCAR has managed to introduce laser inspection, multi-billion dollar TV rights, digital dashboards to replace traditional needle gauges, etc, and yet they cannot replace the old school 5 lug nut design?
1 lug nut... self policing... no more grey area for teams to push.
