Here is one that took me an hour to design with heavy paper and another hour to replicate fooling around cutting the pattern and bending material from plastic milk and juice bottles. It takes a second to install and remove- just hangs over the plastic triangle on the door stays secure when the door is closed. One installed on the drivers side diverts the air flow sufficiently to prevent the build up and release of air pressure that causes the buffeting (sunroof closed, tested to, uhm, much more than speed limit).

 

Chuck, I just "borrowed" your idea, that I saw in another post here or on Rennlist and replicated in cardboard. It does not seem that the shape is too critical, just something that reroutes the wind from between the body and the mirror, so it does not buffet in the cabin.

It seems that several folks are working on it, and there will be a few commercial, interesting ideas coming. I am not quite sure that $300 glue on aluminum wings is the way I will go, but there should be choices soon.

 

I am still amazed that a such a little tab does such a big job.

 

Impressive Chuck!

I drove a coupe before I got my cab. The buffeting from the sunroof made the sunroof unusable above 45 mph imo. In my cab I have gone over 100 mph and the wind noise wasn't that bad.
