As for details on the IS F, here’s what Jason had to say:
This was the client’s own daily driver car. He had a number of customizations added to it including a very low profile front carbon fiber spoiler, special 20″ black wheels and perhaps most noticeable was the throaty prototype exhaust system. The V8’s could be heard rumbling loudly even at idle. When revved you can hear it two blocks away.
Absolutely savage — thanks to Jason for sharing this image, and be sure to check out the other pics from this photoshoot over at his website.
