I need help identifying the front bumper in this picture.

 

It looks to be the Karuma Z. This thread should help you out if you need to find any other body kits for the G https://g35driver.com/forums/interio...tion-list.html

And If you wish to purchase one, R1Autoworks should be able to help you out https://g35driver.com/forums/exterio...dan-coupe.html

 

How is the Karuma Z with fitment, is it a quality bumper?

 

fitment was pretty hard to get it on for me but i eventually got it to fit pretty good, the sidemarkers also get loose sometimes when i drive(i push them in after i get out of the car everytime lol)

 

If you want fitment as close to perfect as possible have a body shop install it. It'll be more $$$ but worth it.

As for the quality, I'm not too sure but I see that they have it available in Fiberglass and Poly Urethane. There's Pros and Cons to both of them, so I suggest you read up on this https://g35driver.com/forums/interio...e-bodykit.html to help you chose what best suits you.
