This may be a dumb question, Is there a max speed at which the windstop will fail? When I look in the rear view mirror I see it oscillating a little bit at highway speeds. It is very well attached.

While the clips hold in high winds, the vibration setting in can and does weaken the plastic. My clips failed and my plastic took off when I had the top down, and at a speed of 75mph rolled down both side windows (don't ask me why I did that - the buttons were just too tempting I guess). It only took a second then wham! out the back it went. Caution is the word on the clips and routine inspection especiall before the summer season is advised.

Mine starts to flex around 75 and one side releases around 85. Can this be fixed or do I have to replace it?

Inspect the clips on the window and on the rollbar and compare one side to the other. It is not always obvious when one is broken.

Just to clarify - top down, high speed driving alone won't knock out the rear windscreen. I have operated my windows multiple times in excess of 140mph. It is actually quite interesting to note the drag effects of lowering a window at high speed. Even cooler is to feel the car slow down when you raise a hand above the windshield.

disclaimer: I officially do not recommend driving at speeds that are unsafe. Routine inspection of the clips/window tightness each spring or summer as stated above is a good idea
