I've got weathertechs on my 06 Runner and they def look really good and work fantastic on the T4R, one thing i've heard from others about the in channel types is that you will hear some outside wind noise because the visors will eventually create a gap in the weather stripping around your windows. MY EXPERIENCES: I do hear a little more wind noise than i did when i didn't have them but it wasn't significant, at least not to ME. I also got used to it so it doesn't bother me at all.
But AVS also makes some nice visors for the T4R also.
