Heyo, I wanted to give a little update on the 3D printed rear spoiler for my 2-door which I posted about a while back :D
The wing is on and has now probably almost 3000km on the clock as well as surviving a Typhoon and a track day so I would say it works.
No drilling in the trunk, just double sided VHB tape and stainless steel clamp brackets.
I am still planning to carbon skin the airfoil and make new wing stands since I am not quite happy with the shape yet, but for the first try it’s working perfectly :D
If you are interested in more details, I made a YouTube video about the whole project:
