    Hi everyone,

    In addition to my previous post, I noticed there is some extra rubber protruding that is not present in the OEM part.

    Is this the same on yours?

    Thank you,
    Alex

      I'll also post some pics with some comparison with the OEM pass/right side I have sitting on the shelf.

      Also, anyone know if there's still a discount code? The original NAM3 doesn't seem to work anymore
      Okay so I finally got the chance to order Matt’s bottom pieces and looking at them side by side with the OEM Pass. Side I have, it’s def not an exact 1:1 OE replacement. First thing I noticed is how floppy Matt’s are in comparison with the BMW one. This is due to the fact that BMW used rubber fused onto hard plastic piece where as Matt’s are full rubber(or at least rubber on soft plastic, but it seems like a single molded piece) (pic #4). BMW’s is also more matte, but that could just be some sort of coating the added for storage? There’s also a lip(?) that doesn’t go the full length on Matt’s(pic #5).

      I guess since Driver/Left side is NLA, beggars can’t be choosers🤷🏽‍♂️

      Pics to be posted later today.

        Hello,

        Long time listener, first time caller. Related to this discussion, I wanted to see if there's any knowledge about the weatherstrip that runs along the outside of the door. On RealOEM, it appears there are two separate options - matte and gloss.

        Google search told me that all M3's were equipped with the matte trim for this piece, and the existing piece on my car looks matte, but wanted to make sure (it may have been gloss when it was new and now is matte due to age - I am not the first owner). Did M3's also get equipped with gloss trim?

        For reference, here are the parts I'm looking at:

        Gloss: 51327890453
        Matte: 51328227625

        ​Any wisdom would be appreciated!

          I believe it was an option or came on the ZCP M3's, but yes i do believe it was available for M3's. The standard trim was matte. This was standard option on ZHP coupes i think.

              The gloss finished trim is a very non-standard and rare option.

                51368194741 is back in stock in Germany with BMW. Some backorders with distributors were already filled, I managed to snag one from Bimmerworld.

                  I have only ever seen the gloss on ZHPs

                    You could do what I did and have the matte trim painted gloss black. Pretty easy work for a body shop to do.

                        Yes! Thank you for that. Just arrived yesterday. With the big upper surround piece also being back in stock, I now have the full collection of 6 pieces. Only cost me $2800 🤪

                          you're a madman! I have a tiny blemish on the upper part but couldn't bring myself to pay up for it

                            Yeah never in a million years did I think I'd spend basically $3k on rubber trim. That's an airbox or a diff. I am not happy about it. But here we are. The rubber on mine is all rotted out, so not much I could do unfortunately. I could tolerate a blemish here or there. I bought the 4 out of the 6 pieces right away (purchased the car in Nov.), and I guess I "lucked out" b/c the big upper surround piece was $500. When the backordered one was available again they became $1500 each. So "lucky" me I ONLY had to pay $1500 for one.

                              lol. I'm learning that this platform does weird things to our brains. Somehow I am envious that you have secured six pieces of rubber and plastic for many thousands of dollars. There is something about knowing you have them, and no matter what happens, you've got 'em. It's really only that left one under the window that was unavailable for a while there that I really need. But I bought both sides just in case.
