I put a roof spoiler on my Beetle my thought was to break up the suction that develops along the roof and trunk. When it is raining I can see how water & dirt stays stuck to my roof 10 inches before the spoiler and on the spoiler itself. The air flows from the higher part of the roof right over the spoiler keeping off the glass for approximately two feet (a guess)if it does reattach as it may not reattach at highway speeds, I have not tuft tested it.

this is my car
