just had the dealer install it, the LED light did not work reportedly, but they found a jumper in the wrong position.
it was the first CTT spoiler replacement by the twin wing profile , not sure if it was a placebo effect or not.
at high speeds found the rear end adhesion to the road is greater, rear window did not get dirty as quick as usual.
Did some research online about the subject and found this study

i think the upper wing act as the positive angle in relation to the bottom wing, vs the zero inclination achieved by the stock turbo spoiler.
also here more technical aspects as of why the combo " twin wing profile " improve the drag and lift characteristics vs no spoiler or single wing " zero or positive inclination" type. in any yaw angle including condition..

Porsche used "plastic" on many parts, especially the interior which makes it a bit cheap if you ask me
some pictures of my recent changes in the interior, working on on the exterior now

Those were interesting links, thanks for sharing. I never considered the aero benefits of the dual plane spoiler, but assume Porsche would have done some wind tunnel testing to make sure it was most than just a visual treat for GTS owners. Car looks well equipped, I bet you can smell all that leather!

If you like the looks, cool, but thats all this is.

hi, need your help on this!
i'm facing the same issue with the LED, it's not working for some reason even though its the same plug as the original GTS spoiler.
what did you mean about the jumper in the wrong position? , how did they fix it and made it work??
