I am seriously thinking about the rear windows.
It certainly will not be for rear seat passengers though, as I took out all of my rear seating a few years back to hold camping gear and the ARB fridge back there.
But they would be good for fresh air to circulate inside, and they simply look cool :sombrero:
I need to watch the installation YouTuber vids some more, and then think about it.
As far as the bulging fender issue goes,
when I was at the PSTOF a few weeks back, a few of us FJ owners were talking about the issue, and none of us have it.
Mine is a fairly early production model (June of 2006) and I carry a lot of weight such as the ARB bumper, winch, camping gear, and I have not experienced the fender rips.
My rig has seen many rough forest service roads and light trails, more so than some of the stock FJs that have gone off road and have fender rips.
Some rip, some do not.
I guess I am in the latter category.
Even if they did rip it is mostly a cosmetic thing.
