Regarding your Silvia S15:
I'm mastering the S15 first, but I plan to move up to DK's 350Z style (or something close) soon.
Where did you find Rays and GTwing labels?? I tried to find it but I must be blind.
Not being picky, but if you wish to make a re-creation of the movie car, the wing wasn't a Nismo. As a matter of fact, the entire car was CWest body, though the closest wing to the movie car is the option right before Forza's adjustable wing.
Also, the movie car had 19in Volk 7-spoke rims (can't recall style name, but it's not in-game. I use Volk's second to last rim style).
Regarding the other cars:
Very nice. If I didn't have an Integra already decked out, I'd make an offer on yours.
GT: Specialist 068
