The supports on my empty body wear out after 10 years and need to be replaced. These racks were recommended, although they were much stronger than the old ones I replaced (stock empty racks were 28lbs, these are 40lbs per rack). Installation was extremely easy, literally taking less than 30 seconds and broke instantly. At first I was in doubt as to how hard I had to pull to open the rear window with the panes attached, but after a day or two they seemed to break (or I'm just used to very strong pillars). If I had to buy them here too I would take the kit to be closer to the standard 28lbs but they seem to be working fine.
