Aerodynamics of a bug

[Gerrelt]

That's one I made , here is a bigger picture of it:



And this is another one:



And this is the one on my own beetle:



I sold a couple in the Netherlands, and one in Belgium.
I am planning to ship them overseas too.

Does it slip under the seal or is it held on with double stick tape or something? I really like how subtle that is, was the shape designed with a specific angle or was that just the angle that was decided on visually?

There's a lip on it that slips under the seal. It's hold on pretty good with just that. But to be sure it won't fly off (and fly through the windshield of the car behind you..), you have to put a bit of sealant on the inside on the left and right. Just in de corner where the spoiler meets the window.

Here's a picture of two of them before installing:


The angle is aproxametly 12 degrees compared the rear windshield.
I was told that anything above 12 degrees becomes an obstruction instead of an airflow guidance.
