Found this diffsuer while searching for G37 Sedan parts. I've done some searching here and all I hear about are the Carbon Signal and Autokits diffusers. Does anyone have this piece? And would it really fit 2010+ bumpers? Because looks like an 09 is pictured. I like the look of this piece, the red light makes it seem more oem. And it's somewhere between Autokits and carbon signal in terms of aggressiveness IMO of course. Also the websites seem kind of sketchy, has anyone ever ordered from either of them?

It looks cool. No idea of it will fit tho man.

 

I made the mistake of buying a sedan duckbill spoiler from that company.. Fitment was complete garbage. I can't speak for this diffuser, but the spoiler I recieved was no good. The carbon fibre looked really weird, it almost had a wavy uenven look to it. Personally I'd stay away if i were you!

 

Hmmm thanks guys.

Drive clean,
Did they refund you on the spoiler or were you stuck with it?


Well, is there any other option for a diffuser? Besides Carbon Signal and Autokits?
Thanks!

 

To be honest I didnt even bother. I had a friend who wanted locally who wanted to buy it for some reason, so I just sold it to him for $50. He tried it out and hated it as well.

The material itself wasnt very good quality, and it was very sharp around the edges of the spoiler so it scratched up my friends paint pretty good

 

Well supposedly the G overseas did get same bumpers as over here



But I just don't see this diffuser fitting since the 2010+ lower "valance" extends to the far, lower corners of the bumper, unlike this diffuser. Just can't think of how a diffuser can fit both 07-09 & 10-14 bumpers well.

FWIW I asked the seller about fitment to 2010+, he asked for photos of my car, sent them and said the diffuser will fit, but still not convinced.

Shame because I like the look a lot

 

The license plate area looks like it is for EURO plates only. I dont see how this would fit on a smaller area (US plates). And yes, how can it fit both 07-09 and 10+ bumpers when they are different?

 

OP don't forget to hit the "thanks" button for Mr. Drive Clean. He may have saved you from wasting some $$$

 

I always forget about the "thanks" button. Thank you lol!

Stownsaint,
This does seem odd he said it would fit after seeing your car. Maybe hes just trying to make the sale.

Bat6wc,
I see how the license plate is different for the euro plates, thanks for pointing it out.

Basically I don't see any way at all this will fit a 2010+ US spec car, which sucks because I was ready to jump on it. I just wish there were more options for diffusers as I'm not crazy about Autokits or Carbon Signal.

 

The options for the sedan (and in my opinion the coupe too) have always been limited. Most likely any place you go thats not on the forum (and some on the forum) will be cheap fiberglass that will need a lot of work to make fit.

You can always go with the WALD rear bumper. Tommy Kaira and IMPUL (Japan) have rear bumpers but again to ship will be expensive, plus they will still need work. I purchased a Tommy Kaira authentic rear spoiler and the fitment was pretty good. Still needed work though and the shipping was a couple hundred.
