Question Carbon Fiber Rear Diffuser

https://www.alibaba.com/product-deta...29c33874iP7SYg
Would this fit on Non F-Sport 2013 GS350?
It say's F-Sport only but I thought there was no difference in rear bumper, only front.

F-sport and non f-sport have the same exact rear bumper. Also there is another thread were someone bought the plastic version of this diffuser and had trouble getting it to sit flush even after modification. Might be worth a try.

i have an abs version of this, if you look in the picture you will notice its missing the side and top mounting tabs. these would have to be fabricated, making install a little more work than i would like. there is a new aimgain copy on ebay now for 120ish, that looks promising.

@itsRaymond has this rear diffuser, along with the NIA lip on the sides of the rear bumper. Looks like perfect fit:
I'm not a big fan of how the fins point strait downwards, Aimgain has is a angle to it, but then again the ebay one is only $120.

I also asked a couple months ago, they don't sell the carbon fiber version of it even though that's the one in the main listing picture. probably worth asking them again.

Just a heads up, the one OP posted and the one ItsRaymond and the link you posted look different. The one OP posted looks a bit more aggressive and comes up a bit onto the bumper.

Yes they are two completely different diffusers. The one OP posted is most likely going to have a bad fit, like others have experienced, but one ItsRaymond is a perfect fit.

Ah got it, I misread your wording. Also just wanted to point it out in case OP didn't notice.

The diffuser in the OP is pretty aggressive. You'll need to have a mean looking car to back it up.

OP's link is sort of the replica Toms diffuser, here is a pic of the real one:


The one I posted is the Aimgain Replica, here is a pic of the real one.


This is on the RC F but a square exhaust setup would be cool on the GS, reminds me of Mercedes AMG tips

If you are interested, I don’t think I will be installing mine anytime soon.
