No, as that's the normal urethane cover for the crash bar. The part we're talking about attaches to the bottom of said cover.

It's all one piece.

Considering the person that posted before you owns a BRZ, your statement is false.

The topic is of a 2017 86..., and I’m pretty sure the BRZ is also one piece.

57704A in the link to parts your provider shows it to be all one piece.

The person that posted before you, that you are replying to, that I was referencing, owns a 2015 BRZ.

The 2017+ BRZ has the same rear bumper as 2013-16.

So tell me... how is the rear bumper all one piece? The add-on rear lip is still available:

Picture so he can stop trolling.

LOL. Is that what you guys have been talking about this whole time? That's not a diffuser either!!

Yes, we heard you the first time when you said "there is no OEM diffuser"

Yes, this is what we've been talking about the entire time. If you want to argue about functionality, we are not talking about that. There's a reason why this subforum is called "Cosmetic Modification".

Remind me not to come back in here.
Why does this even exist?

wow. you guys are still doing this?

I was taking about the bumper cover and it’s integrated “valence”.

Subaru markets the optional diffuser as functional but who knows.

Reminder: don't come back in here.

I'll stick with my Velox (Verus) diffuser that actually diffuses.
