I was just told about this the other day that it was mandatory for all heads up classes. But then checked on NHRA and it looks to be for all the classes, but nothing under the Sport FWD class. Are we clear on this or what?the only change they made was the Slick size from what i can see.

 

thats what i wanted to make sure, becuase i was told this applied to all the heads up classes now.
thanks. saves me money. lol
