I had to use zipties to make sure mine didnt disappear- recommend securely fastening them!

 

Guys,

Reviving an old thread here. I am interested in putting larger ducts on my MY04 996tt running standard brakes. Just to confirm, my options are:

Standard GT3 which fit without modification, part numbers 997 341 483 92 and 997 341 484 92

996 GT2 which need trimming in places, part numbers 996 341 117 91 and 996 341 118 91.

GT3 Cup which need trimming in places, part numbers 996 341 117 90 and 996 341 118 90.

Does anyone have any pictures of what needed to be trimmed on the cup ones?

Is the above correct?

Edit,

Just found this thread which answers some of my questions:

Both the GT3 Cup front and 996 GT2 rear ducts are a direct fit with no modification required. I can verify part numbers for you later today. The GT3 Cup front ducts are basically the OEM 996tt ducts with an additional deeper plastic scoop riveted onto it. Simple and effective.
