Aero mainly. We trick f'ed the NASCAR TECH bozos for so long before they got their romer arms and grids , that this is just NASCAR payback time.
I'm sure Nascar will step in and put restrictions on the ford's and Toyota so they can win again. That's the way they have always done it.
A question like this pipped up a month ago. Who knows. I work for Hendrick and I am baffled. I guess you have to take the good with the bad. We can't win them all every year.
