Just from experience....don't run your car over 65mph for long periods with all your windows open. Back in 1988 I blew out my headliner in my 1967 Coupe and it was in excellent condition prior to this. Anyone else have this experience?

I havent replaced mine yet, (its wasted also) but previously on my other older camaros I never had a problem. I did do a interesting thing, I went to a local shop that does seating and other headliners, I asked him for a piece of vinyl (black) large enough to cover the headliner. I removed the rails that run in the liner, bought a large piece of cardboard looking material (from the same shop) glued the vinyl to the board and cut it to fit using my old headliner, it went in place very nice, the interior trim held it up (as well as my lighting and coathanger screws ,sun visor screws etc) and I never had any problems like that again , and it also looked really nice and I could armor all it..

I have a non A/C car and have always driven on the highway with the windows down. As far as I can tell, the headliner is the original one.

hmmm mabey I had bad stitching in the back about 6" from the rear widow. but the whole row of stitches blew out due to wind force. Please note that I had all 4 windows down. That may have been a factor. Whether it was due to a windy day increasing the force I cant remember. And I was probably trucking along around 70-75mph. Just something to look out for.

Not that any of us would ever exceed the speed limit, but I would be real concerned about the back window going balistic at very high speeds. Try explaining that to Mr. Officer.

Never had that problem with my original
Headliner at that speed with all windows down. You must of had a seam that was deteriorated.

Jonesy almost said it. I had one blow out under high wind. It was just starting to rot, the threads come apart and just start to unravel. Moisture and age don't mix. Anyway, new headliner no problems.
