Re: the function of rear wings...

[SCIROCCO2@t-online.de (Dirk Schneider)]

Mark,

you didn't get me right.
Of course I know that a spoiler works with airstream :-)

In my bad english I was just trying to explain that
the 16V wing is designed too heavy , the GTX wing is
much lighter and does the same job.( maybe better due to the horizontal slat... )

The Scirocco rearwing ist there to cut the air behind the car
this prevents swirls and reduces drag, like others mentioned before.

There is some downforce also, but that's a side effect, not the main thing.

Greets
Dirk

They are called spoilers because they SPOIL the
airflow around the car, hence the air pushes down on
the spoiler who in turn pushes down on the back of the
car so the rear axle has more traction, as the rear of
a car has a tendency to lift at speed.

No no no, it has nothing to do with the actual weight
of the spoilers... It works with the air flow, and you
have to drive fast to notice anything usefull. If it
was better, it was better by design. Of course any
smartass lugging around bricks in the trunk will get a
better traction, but this is different. :)

You will have to really drive it hard and fast to
notice something, not just drive around. :) At over
120-140 Kmh you will have more overall stability.

In fact if it was made in Germany, it is the law over
there to have functionnal spoilers on a car. Any
aerodynamic package needs to be functionnal to be
legal on a car.

I read once that the VW Scirocco 16V body kit (as seen
in N-A) is good for 1 mpg at highway speed. So the car
slices better through air. You probably need less HP
to hit 160 as well (Kmh of course, eh I am in Canada).
Nothing major of course, but better than a kick in the
butt.

I am sure that you get an equal benefit from the
zender body kit, It probably is fully functionnal as
well as good looking.

So please have a good laugh next time you see any big
ugly useless spoiler on a car...

Cheers
