Preparing to get into a 2012 370z Nismo...

[VAUROS]

All -

I just recently sold my 2012 GT-R Black Edition (she'll be missed) and I will be getting a Nismo 370z. I'm sure you're wondering why I'm downgrading from a GT-R, but let's just say that I prefer to do all of the 'driving' myself. Nuff said.

Before I buy it, I'm basically putting together a list of possible mods I want to do as soon as I get it and I need some input. See my questions/list below:

Exterior Mods:
1. I've found the OEM black Nissan emblems and the 370z emblem, but where do I get the OEM black Nismo emblem?
2. What is the paint code to get the door handles painted?

Wheels/Suspension:
1. Since the Nismo Z uses different springs and struts from the stock Z, which lowering springs should I use to lower the car? I've found the Eibach and Tein springs but I was wondering if Nismo has some OEM lowering springs? Which are the best?
2. What are the widest front and rear tires that can be put on the stock OEM wheels?

Exhaust/Intake:
1. What is the best intake/most popular intake system for the Nismo Z? I see that Injen has a Nismo Edition intake but I don't see one from Stillen.
2. I don't plan on replacing the stock exhaust, however, I do want to replace the mid-pipe so I can achieve a louder sound over stock. What is the best mid-pipe replacement for the stock Nismo exhaust?

Thanks in advance!
