I bought these seats a while back for my crx. All of the bride seats (fake or not) have real bride fabric. However all of the fake ones have a cheap fiberglass case for them. The real bride seats either come in kevlar, carbon, or a grey looking back. All of the fake ones have the black backing.
Please correct me if I’m wrong but all of the research I have done has led me to this conclusion.
From what i can tell all the zeta 3’s have a black back (no metalic) and everything was ment to be a simple basic race seat.
I don’t care at this point just make a offer so i can get some parts i need.

From what I can tell the picture of the seat has a metalic back and at the bottom where you select what color you want you can select carbon fiber so all the zeta III’s are not black. And never were from Bride.
Send me a pm, I would like to see them in person and how i fit.
