I have always felt it is a waste to go thru all that when it doesn't change the bracket you can enter or the money you can win (except if you want to run S/G). I can run S/P or Pro anytime running mid-10's with a 6-point roll bar, no window net, clown pants, fighter pilot physical exam, or cha$$is certification.

But there are others who feel they have a better chance against the pipe racks running a quicker door car, one guy I know went out and bought a chassis car just to pick up .0005 in consistency.....
