Andy, the car is looking AMAZING, I love what you've done with it man. I agree with whoever said it, but Deepdish rims should be in your near if not immediate
future, I think it would accent the kit more.
Also, Greddy actually makes a pretty good Exhaust and Turbo System for the 350z, or so I've heard. My friend has it on his Z, he's only had the Turbo and exhaust kit on for about a month so it's not really much on wear and tear yet, but all i know is his car HAULS!
Anyways, back to the fact of your car, dude... NIIICE
