like a lot of high end performance cars, at high speed the vacuum created wants to suck the windows out, this feature prevents damage.

 

Hmm, not quite. Like Skids and roadagent said, it is simply to clear the weatherstripping.

Oh my. Um, this was a joke, right? Can you explain to me, in layman terms, how the window rolling down a 1/2 inch when the door is opened prevents damage from a vacuum created at high speed from this high end performance car???[sm=dontgetit.gif]

 

I don't know about clearing the weather stripping but corvett been doing it for a few years and there reason is so you dont have to slam the doors. Have you evere had a car tight enough you had to crack a window to shut the door easier.
