sealing around headlights

I also plan to redirect air into the front wheelwells by opening the headlight housings, replacing the lights with small diameter lens-type headlights.

mikeemans, the idea is to seal up the high pressure area in the front of your vehicle. Air hitting the front of the van makes it inside through gaps and openings, swirls around and creates drag. You may want to consider making flat covers if you have don't have flush mounted headlights and "basjoos" the gaps.

Phil, thanks for breaking down the aero gains on the VW. You are an inspiration and an asset to us all. I am eager for warmer weather to start on my belly pan and receiver hitch-mounted boat tail. I welded up the plug-in "stinger" over Christmas vacation. I should be able to start building from that this spring.
