Sorry, new to the Audi scene...B4 means 1993 and up right? And B3 was before 1993...?
Looking for the stock style spoiler that was for the 93 90.

other way around. B3's had the alloy 2-post spoiler and B4's had the fiberglass 4-post spoiler. And a B4 spoiler with the 2 center-posts removed and glassed-over will flutter, fracture then grenade on the rear decklid at about 85MPH. Ask me how I KNOW this!?! There's a VERY good reason the B3 2-post alloy spoiler survives with only 2 support posts at each end and it's due to structural rigidity being TONS more rigid than fiberglas. The B4 rear spoiler MUST have 2 extra center supports or it EXPLODES at speed without em!!
Much of the confusion related to B3/B4 rear spoilers is related to previous owners buying/installing whatever they could find/buy in a junkyard and installing on either chassis and even Audi dealerships selling what they had in-stock or ordering and installing/retro-fitting either spoiler interchangeably on BOTH B3/B4 models.
B3 is the older, heavier, more rigid 2-post alloy spoiler and B4 is the lighter, less rigid 4-post fiberglas spoiler. No matter what chassis either spoiler is pulled from today cannot change/alter those facts.

Are you sure about that? Mine came with this alloy one, and it definetely does not flutter at speed, and as you can see from the pic, was made for the B4 decklid.

Yes, positive and as my post states "fluttering//fracturing grenading" is limited to the B4 fiberglas spoilers that had its 2 center-posts cut out/glassed over and not the more rigid, 2-post B3 alloy spoiler.
There was a part number/picture in ETKA for the 2-post B3 alloy spoilers YEARS before the fiberglas one appeared in the 93 ETKA.
And as I've already said "either spoiler fits either car identically."

Well at any rate...The pic I took of the black spoiler for my fellow Canadian in port Hope Ontario is fibreglass and came off my 1992 Audi 80 b3 and has the 2 centre posts.
