Retrofitted back seat wind deflector on 2016 S63 cabriolet
As you can buy it including the connector plastic parts, does anyone of you retrofitted it to 2016 model? It helps a lot with the wind and I would really appreciate that.
I am just scared if there is the hole or anything behind to screw it in…
See pictures how it looks. Thank you!

As I had the MY2016 before, and the electric, rear wind deflector looks fancy, but does not really help at speeds above 80-100 kmh, I tried to do a retrofit back then also. When using these original parts, you also need 2 new back panels (with the right holes in it for mounting), including trim, and including labour it would be around Euro 2,500-3,000.......that was a little too much imho.
After a while a made an even more expensive move.......upgraded to a MY2019 S63 convertible, including the wind deflector! 😎 And yes........it really is a very useful option, you can drive open at much higher speeds without be blowing away (I did max it to 287 kmh on the German Autobahn with it 🙈

PS: if you are not afraid to make the holes yourself in the back panels, it would be much cheaper, but I did not dare to do so....

And thank you very much for the answer. As you said, rear wind deflector is fancy, easy to operate and hide, but I don't see a difference with or without it - maybe for the rear passengers that we do not carry most of the time. The original service also said the same as you did - you also need two back panels with holes. But, and there comes the point: I saw this video (it is C class, but this part will be the same):
I know that original dealer does not want to do anything else than original, so I do not expect them to screw the holes in expensive panels. But - the important part is not the hole in the panel, but the rest - what part is the screw mounted in. It definitely has to be screwed in the solid part, not just the panel as the wind can be quite strong. So I am now thinking... if mercedes says you have to order back panels and they can do it - is there a hole also in pre-facelift model?
If you find a good and handy mechanic, making two precise holes does not cost 2,5k USD :-) I ordered the original screws and mounting accesories from Mercedes (was 80 EUR) and I will probably remove the back panels and see whats behind them. I will make pictures as I think this might help a lot of pre-facelift users who are facing the same issue.
Anyway, thank you very much for the answer and congratulations to a facelifted model! Greetings from sunny Prague, Czech Rep.!
I am so happy for that as the difference with the windschott is like 80 percent greater comfort than with the original behind the back seat.

For all interested - all is done within 1-2 days and you can connect it with a trip to wonderful Prague :-) I will be happy to connect you to a right person if you need that.




I am having a difficult time confirming that these exist - every photo and video I’ve seen on US 2018+ cars has not shown them.
Thanks!

I could only recommend to find someone with original factory wind deflector mounts (2018+) and measure it from the original instalation. Otherwise, as you say, you drill the hole only once and the panel costs a fortune...
First unlike the video's description my side panels have 3 screws not 2 holding them in place.
The location of the hole is about here.
Turns out that 'close does count' because the outer piece is significantly bigger than the hole.
Third, While the unit is OEM it does NOT fit my USA 2018 S63 Cab perfectly. Top view is great. But side views show that the curve of the panel must be somewhat different than the Euro models.

All in all I'm good with it and now have a wind-deflector installed. It was very much worth the effort!

to the panel.
It makes the roof down experience, especially at lower temperature, so much more enjoyable. You can actually feel the AirScarf working, even at motorway speeds.

Finally after 3h of hard work by my trusted bodyshop I managed to put it on... and definitely I can feel the difference! PS there was no need of stripping off the seats!
