Hey,

Having some spare time at this current moment and i came across this on fleabay..Vortex

In the diagram it looks it it has increased drag to be honest lol but i was wondering for the clever people here..does this actually work? I presume it wont really work for fabia's as they're hatchbacks.

i aint even going to comment!!!!

How many new cars do you see fitted with them?

1, the evo 9/10 lol :P

Go for it, then you can tell the rest of us how good they are......

thats the sort of tat product you'll be able to buy from auto jumbles for 99p , along with the rest of the rubbish they sell

"Apparently" the way it works (the proper ones), is that theres 'reverse' airflow [i.e. air flowing back to the front of the car] on the glass of the rear end of saloons, the fins creates a twist in the air of the normal forward airflow to counteract the 'reverse' airflow to create a vortexed 'reverse' airflow... clever that.. Basically it breaks up twists of air from the rear by creating smaller twists before big twists of air at the end of the car, this works with cars greater than 12 degrees of drop apparently.

I would think it does work, otherwise why would racing cars have it ?

You might notice a benefit...

IF you drive a McLaren F1, Dauer 962 etc at 200+mph, and worry about losing 0.05 seconds exiting a corner.

Racing teams have done everything possible, this is a last ditch tweak, that might (if theyre lucky) knock 0.01 second off a lap time. I don't think any road user need consider these tbh.

Doubt the racing teams stick theirs on randomly with M3 tape mind :p

and don't forget you will need the use of a wind tunnel to get them in the right place...or it could make things worse
