They become effective at about 400mph.

Dont let my humor be the reason you dont get them if you like it. I just find it humerous to see these cookie cutter VW's driving around thinking they are cool and unique. The douche behind you has the same set up with a different color douche! Thats typically what I yell at them!!

They were actually designed to stop dirt from accumulating on back windows of hatchbacks like the TDI hatchback. By breaking the windstream that would swoop down on the back window right after the rear roof edge. Apparently it worked. I believe Acura also had something similar.

Do they serve the same purpose on a plane? Can imagine too many windows getting dirty while going 400mph!

Different purpose but same idea, to break the windflow over certain areas of the wing.

sorry to bring up an old post, but I can actually explain these a little. While Coby7 was right about them breaking airstreams and windflow, I know on evos it's actually been proven that with the stock spoiler and having the vortex generators on the roof it actually adds 15% more downforce on the rear axle, just by baffleing the air that comes across the car.

lol actually, the mr evo is the only one that comes with them. As you can see by the pics of my evo, which is an mr se, I don't even have them.

Here is the research for those who like to see the research and graphs/images of them
