Porsche sells the originals (around $6k per set).
There are a few options for the fuchs replicas:
- WheelDynamics (OS Design and OS Design II) => http://wheeldynamics.com/porsche-cars.html
- Hartmann also makes nice versions => https://www.hartmannwheels.com/porsc...orsche-fitment

There are others as well, but these 2 come to mind quickly. TireRack no longer has the Starke Design replicas.

 

997.1 GT3 or 997.2 GT3. The .1 wheels I'm running on my wife's NB C2S (same body as a GT3 don't need any spacers, nor have any room for them. The fitment is so good, I based my custom Forgelines off those sizes and made a few mm tweaks here and there based on the previous 4 sets of wheels I had on the car and how those fit and looked. Went 3 mm further out in the front (et 53 for 8.5" GT3 wheel and et 50 for the Forgelines), but actually pushed the rears in a few mm.

I've had from an et40 to an et53 on my 997s all with 8.5" wide wheels and did not notice any steering effort differences between any of them. With the et40 I did notice a very twitchy and unstable feeling at high-speed with the only variable being the wheel offset (same make and brand of tire, same wheel width, same alignment settings, same diameter, same air pressure - only difference was the offset).

 

Looks good. These are SpeedArt wheels
