^G35papa is correct it does fit the Nismo Aero bumper. I thought you were asking about fitting it on the stock 03/04 bumper, but I realize you have the Nismo kit now after reading your sig.

 

Sorry, just to clarify, cause i am confused.

Are you guys saying the standard 03 Sedan Chin Spoiler will not just unscrew and fit properly onto an aero bumper? Do I need to get a different chin spoiler or can it be modified to fit?

I got my aero today, but won't be able to see if the stock chin spoiler will fit for till at least next weekend.

Cheers guys.

Oh and my bumper doesn't look like the one candlestick has, I have the extra stock looking front.

 

^ The factory chin spoiler was designed for 05/06 sedans so it will not be a direct fit for the 03/04 Aero kit bumper. It can be modified to fit the 03/04 aero kit bumper. This can be more pain than it worth if the body shops in your area have high labor rates a lot of body shops will just say it doesn't fit and we're going to charge you $$$ to make it work.

 

Not sure how a factory 2003 Sedan chin spoiler can be designed for a 05/06 Sedan Bumper but thanks anyway!

I think the gist of what you were trying to tell me is it won't fit without modding.

Ok cheers!

Ok scrap all that, i think what I think a chin spoiler is is different to what you guys are referring too. I'm talking about that little bit of black plastic that is on the bottom of the front bar. Don't know what it's called. I take it you guys are just referring to an extension of the bar. Sorry for the confusion.
