I see the biggest potential for improvement in front side aero coming from a flush upper grill block.

Also note that higher speeds will be more revealing of aerodynamic benefits of lowering CD
Yes, the grill block is coming. Since I want to make it look nice, I need to find some extra time to make it. I don't want a hacked together one. Though, I may do some painter's tape testing before I even take the time to make the grill block.

Maybe I will test the air dam at 60-65 mph instead of 50.
