Of course it depended on raising the pressure which NASCAR took away!

They also changed the rear spoiler a bit to remove some of the draft advantage.
NASCAR's always looking at technology "advantages", and then changing the rules to take them away, sometimes temporarily to give others time to incorporate similar changes to keep the field close. Often it seems there is no justification for the rules, other than it being like Momma used to say, "Because I said so, that's why!!"
