I can believe that it doesn't make much difference on something with a drag coefficient of a Formula 1 car….. but I don't think anybody with a Mopar will be that lucky. LOL

On my little beasty - the front and rear spoilers have really settled the truck handling down at speed, but still unsure whether it's help or hurt the ET and MPH. A block-off plate in the grill helps by about 2 mph and about 1.5 tenths. I guess it's really tough pushing a barn door at 130 mph.

At speed the back lexan window is sucked backwards toward the tailgate. I still need to try and solve that if I could. I forgot all about pursuing that part of the aero equation.
