Got the belly pan installed this afternoon.

I'm convinced it's going to make a significant improvement to the flow on the bottom of the boat tail. The middle 25% or so of the belly pan is a straight shot between the rear control arms in line with the plane of the bottom of the boat tail.

One thing left to do: I'll do my best to blend/transition the control arms back to the boat tail as well.

All in all, I figure 50% of the boat tail bottom will have fully attached & relatively smooth flow, vs. 0% smooth flow now.

Unfortunately, it's rainy today, so I can't do tuft testing. Tomorrow looks decent though.
