I have already blocked my lower grill and upper grill on the Mirage. The only remaining area that is open on the car is the fairly large gap between the hood and the front bumper cover and headlights. I am looking to close that gap.
I measured the gap the other day and its roughly 3/8" wide. So, while it is a thin area, it extends all the way from one side of the car to the other. The width of the car is 66.5 inches. So, lets be conservative and say its 55" of hood gap. That still gives us about 20.6 square inches of opening. That is the same as just over a 5" hole in the front of the car.
There is no rubber gasket under the hood at all, nor on the bumper cover or headlights.
My question to you aero guys is, is it worth trying to fill the gap so its relatively flat? Or, should I just put in some weather stripping wherever I can to block it off? This would likely be about 2 inches back from the opening.
