I recreated it to the best of my Forza abilities. It's a pretty cool Porsche, if you haven't read the article on Speedhunters (It's been posted below me too) then here's a link:
Here's a shot of the rear end, I tried to replicate it as best as I could, down to the aero holes. The one thing that bothers me is the Porsche logo. It's curved, but I can't fix that. There's an Aero option to put a Porsche logo on there, but it's silver, and I wouldn't be able to put the Gold 911STR badge either.
So yeah, there you go. If there's enough desire for this (It's on the 911 Carrera RS) then I'll put it up on the Storefront under my XBL legory.
Now on the Storefront!
