Retrofit ducktail 991
#91
Joe's experience is similar to mine and I did pretty much exactly what he did on the install other than I had the shop that painted it install the ducktail. I think as long as you have the PASM Sport front lip the aero is balanced from the factory perspective.

So after reading through all the duck retrofit threads, I have read a lot of misleading and interesting suggestions to get things working. After working through everything and getting everything installed here's is EVERYTHING you need.
The part # you need is 991-044-800-78 - This will include an extra engine lid cover, as Porsche doesn't recommend you use the GTS engine cover on the duck for whatever reason. The best price Shipped I found was here as for Californians they offer free shipping and no sales tax. This box is HUGE so most places charge 100-200+ for shipping. NOTE: I have seen thread stating you need some $1000+ mounting kit, the above part # includes EVERYTHING you need to install the duck including the mounting plate.
The installation is relatively straight forward, just use the active spoiler removal instructions that Plenum has posted here.

Once everything is installed (1-2 hours) you DO NOT need to re-pin the harness, a lot of people above stated they did this to get their brake light to work, but if you do this the proper way and get it coded at the dealer you DO NOT need to move any pins in the harness. IF you decided to move the pins as stated above your brake light will start working, but you will always get an annoying error message whenever you reach 75+MPH. If you NEVER exceed 75MPH or don't care about error messages then just re-pin the harness as described above. Otherwise, do yourself a favor and just get the the duck programmed by the dealer.
NOTE: I DID NOT install the front Sport Design Bumper nor did I do the sunroof module and my car has yet to flip over or display any bad handling characteristics.

Yes the GTS one does work fine, not sure where you save 1500 dollars? There are other part numbers for the Duck, but they all cost the same, but this part number give you extra parts for free essentially. You can get the extra decklid and sell it on ebay or whatever.

Thanks for the great tips. I installed the ducktail and took it to dealer to have it programmed. The programming successfully took care of the wing deployment error above 70mph. However, I am still getting the third brake light error and third brake light does not light. This is the part I am not clear about- Do I have to re-pin the harness in order for the third brake light in the ducktail to work and not get that error??? Or, did my dealer not do the programming correctly? Thanks In advance.

I have always wanted to do this mod and once I made the mental decision to keep this car indefinitely I went for it. If you are local SF Bay Area, I am happy to help with your install. It's like a 2hr deal, especially with two people.
