in channel vent visors
There is a lip that fits into the window track. You need to flex them to get them in. Not a problem in warm weather. I do not notice any wind noise from mine. I have the weatherguards. One thing you want to look out for is if you are getting the ones for the back windows, look to see if they cover the rear fixed glass or just the opening window (weatherguards cover both). Also look at the front end (near the mirrors) there are different styles.
This could actually go either way, depending on your personal opinion. For example, I do not like the weatherguards that cover the entire back window, I prefer the ones that only cover the opening window. I especially do not care for the way the weatherguards look where they cover the divider in between the opening and fixed window. But it is all a matter of personal opinion...
