John, Just wanted to let you know what I did before I added adjustable shutters and a belly pan to my red VX.

The VX has a grill opening that is 5 " X 24". When I added the 14" air dam that covered the grill opening I drilled 4 - 4 inch holes in the air dam directly in front of the grill opening. 2 in front of the radiator and 2 in front of the A/C condenser. In the winter I covered the 2 holes in front of the A/C condenser with Gorilla duct tape and only left the 2 - 4" holes in front of the radiator.

I never had any issues with radiator cooling or A/C with this arrangement during the 18 months it was on the car.

It is my opinion that you will need some type of cooling holes directly in front of the radiator and A/C condenser for them to operate properly in all weather conditions.

Hope this info helps.
