Looking for a part...

I'm not sure if the image will show up, but it comes from a picture from CCWheel.com
If you can't see it visit their site gallery, it is the C5 SP20, only convertible in the gallery.
I was looking for that mod part for the convertible door. I don't even know what the name of that part even is. I was wondering if anyone knew of one that has this and how well it was compared to the blocking from the rear turbulence.
Also wanted to get it, so if they can provide a why I could find it, please let me know.
