PD needs to get the gun right. NASCAR does not use a single locking nut system like DTM, F1, ALMS, etc. They use the old school 5 lug system like on a real car. Personally, I'd like NASCAR to go to a single nut system, it certainly would help with safety. And safety is a big deal with NASCAR.
I would love to see NASCAR allow one of the top teams take a Sprint Cup car to the Ring and put a proper setup under these beastly cars. The COT is not an easy car to drive and that's on purpose, to help create closer racing.
