Metal clamps in weather strips rear seat windows
I would never place metal clips on any internal part of my windows due to possible friction or damage. Therefore when I bought the front seat and back seat channel deflectors I had to throw away the back seat deflectors, literally throwing away over $50.00 of my purchase. If you err on the side of better safe than sorry as I do, save yourself the money and garbage bin space... just order for front seat windows and you will love the product.
AVS External Ventvisors
I had been using in channel ventvisors however the window sensors where affected causing the window to go down after trying to raise it. The only issue with the external is that I have center door chrome panels between the windows and the external had to be placed on the outside of those chrome panels.
