From what I see that car also has a Unibrace fitted.

....Are you sure? Wouldn't they have fitted their own Summit cross braces?

Yes, there's a bit of it to be seen on the left and right of the tunnel.
On a side note: You might also find some inspiration here:

Seems they are trying to get the wing out in more undisturbed air

Thanking You!! :drinking:
Now where can I get one!? (if not too expensive). I don't really need one but I don't really need some of my other mods either.

I also want to have a rear diffuser but this is a costly job since I want to change the whole exhaust with the new diffuser.
But both these chapters require spending money and I prefer to spend the money on going to Hungaroring and/or Nurburgring instead. There is enough time to do all the mods...

The biggest challenge is you need to remove the rear exhaust muffler. This implies to
content oneself with a center muffler or even without any at all.
The diffusor itself is made with just some cheap parts (you already know this example):
The big advantage of a diffusor is it provides downforce without any drag penalty worth
mentioning (which a wing has besides the cost).
BTW, there's another 'cheap trick' which cannot substitute a wing, but will at least reduce
lift by some 10 N (at 200 km/h): a gurney flap. It's easily made by some piece of plastic
and fitted to the roof spoiler before you visit a track.
Unfortunately most of the known literature depends on mounting a gurney flap to wings.
Nevertheless it also works on a rear spoiler.
