what the heck? That doesn't make a bit of sense. Nailing three of them to the wall almost assures the fact that the teams will be changing their minds about trying anything freaky for Phoenix. They caught SHR, Penske, and Gibbs cheating. I would say Nascar sent a message. In case anybody forgot, they call Nascar the sanctioning body. (those L1's are sanctions)
Aero cheats are probably not needed at Phoenix, or at least not needed as much as they will be at a mile and a half.
