The trim needs to be a tight fit for obvious reasons. This requires the trim to be pushed into the slot. In doing so too much pressure can be exerted and the older more brittle glass can crack. It did so in a couple of installations. Because of this I withdrew the seals from the market.
Probably sold about 50 sets and have them fitted to 3 of my own cars. Better to be prudent than see expensive windshields being broken.
Yep, I had to trim mine down on the driver side towards the top. I could totally see how someone could damage something by trying to force it. To bad cause I think it was a great product, perhaps they could be made with a softer material to allow more compression? (Assuming you probably already investigated that)

I installed several of them and it takes some care to cut them down, fit, re-trim and do it correctly. One day I was doing one and a buddy was doing his (first timer) and his windshield cracked after the stuff was installed, an original one at that.. He forced it in instead of gently pushing it in place. I was going to fit them to my car but the new windshield install didn't leave enough room for me to do so. Each one is different, especially if a previous windshield was put in, in the past. Was a good product but I agreed with Roger that pulling it from the shelves was the best way to eliminate issues with people installing them wrong.

Mine cracked also...not sure when after the installation but...if i didn't point it out you wouldn't see it. Its a shallow 1 1/2" arc in the black trimmed area on the passenger side, half way up.

Definitively some sort of pressure point. This is a replacement windshield and the rubber trim was exceptionally tight to put it. my guess is the sealant/adhesive application was too thick on the replacement windshield . I almost gave up on it, but with some soap it went in smoothly. no other issues now in a couple of years. It did cut down some wind noise.

A little trimming and some soap on install and mine went in fine and are still there. No cracked glass. Now when I go to replace the windshield due to age/pitting, Iĺll have to pull them out.

I recommend getting the Porsche sealing strips and GTS trim. The trim is cheap, the seals... Not so much.
I don't see any reference in PET to different sealing strips and trim for GTS. what is the difference and benefit?

Fitted from 91 to 95 ---- PET Illustration 810-000 item #36
GTS Windshield Rubber Side Seal Left 928 559 519 00 70C
GTS Windshield Rubber Side Seal Right 928 559 520 00 70C
All 87 to 90 have the correct trim already. Earlier cars may need the later trim.

Does it have the "Do It Yourself" manual transmission, or the superior "Fully Equipped by Porsche" Automatic Transmission? George Layton March 2014

928 Owners are ".....a secret sect of quietly assured Porsche pragmatists who in near anonymity appreciate the prodigious, easy going prowess of the 928."
