What are the spoiler options that are compatible with a GTS decklid for a 991.1 C2S. I noticed that a lot of options, including the factory ducktail require the standard decklid slats. I’ve already got the GTS decklid which I’m not so keen on replacing.

The one option I know about is the Moshammer spoiler.

 

The original slats fit the Porsche aerocup wing.

 

is that the same as the “Cup Aerokit Spoiler” on Suncoast? Looks great with your GTS decklid, but in the description on Suncoast it says that it’s supposed to go with the non-GTS decklid slats. Odd, I wonder if that is optional.

Looks like there’s another post with basically the same question, and there are people using the aerokit or ducktail with the GTS decklid. That’s what I was searching for.

 

Yes, I purchased the aerocup spoiler from Suncoast soon after I purchased my CPO GTS. It comes with the wider slat grill which is easily removed and I replaced it with my narrow slat black one that came on the car.

I won’t swear to it, but it would appear the grills are interchangeable, so if you had a ducktail with OEM wide slats they should be replaceable with the narrow ones. If it’s not an OEM part you would have to find out from the vendor if they are using the OEM slats and the factory anchoring points. If so I believe you could change it out with your black slats.
