Windtunnel results MK1 83' spoiler
 

Hello,

Since July I am the proud owner of a Dutch MK1 83' and recently I have found something really interesting.
I got aerodynamic results of a Volkswagen MK1 with and without a zender spoiler (I believe Zender, I don't know for sure..)
Apart from the fact that this find is very interesting I am wondering if this is something common and possibly add value to the car?
The results and description are in German logically.

Looking forward to hear some expert advice 😉

Thanks in advance,

So that is what it should've looked like.
But, I have a graph and table with the downforce results. So a before and after. Was this common to get with your Zender spoiler back in the day when they could be bought new?

It was included in the original package with mine. Was a Kamei-spoiler though. Maybe it was a 'Zeitgenossen'-thing?

You are right, it is a Kamei spoiler. So this isn't any special? Too bad, I will keep it in that case.
