I've been shopping for a 997 GT2 replica wing for a while now but there's not much available. One choice was one made by MA Shaw which is a complete deck lid but it's very pricey:

The other is a recent development by NR Auto but it's a bolt on to the original deck lid and half the price of the MA Shaw wing. Interestingly they decided to shroud the whole deck lid but it poses one problem that seems to be subjective. Since it is a shroud, in some applications you can see the edges of the deck lid bulge next to the fender and/or tail light. Look at the pictures and give me your opinion, the black car seems to show less bulge of the deck lid and the white more bulge. Keep in mind, quality of fitment of NR Auto body parts in my past experience has been stellar. If anybody else knows of any other 997 GT2 replicas, please let me know.

 

personally I prefer the whole thing.
