Regarding the TMI headliner . . . well, I received serial number one or two that was sold to the public. With that said, I would say the fit needed some improvement, especially in the areas where it fit against the front and rear windshield. In fact, at the rear glass I will need to fabricate some trim to make it look "right" and cover the gap.
Check out the install of one of the more recent productions on camaros.net. They selected the vinyl covering which I really like but was not available when I purchased mine (only available in Unisuede). Notice the picture of where the headliner rolls up into the molding at the top of the rear glass in Post #5. My headliner does not do that. If it did it would fit better and I would not need to fabricate the trim piece to cover the gap.

So in short it looks like TMI addressed the issues with fit since I received my product. It would of been nice for TMI to contact me with the information about the improvements as I happened to stumble across the newer pictures on camaros.net looking at to fix the issues with mine.
