I did this to the panels on my 2021 Makai. They were popping completely out with just stock ballast bags. I plan on going back to replace the wood 1x4's with some black painted hat channel to make it look better. The metal that you see in them now is what came factory. I think this is really a poor design to be honest. The metal they put in there to prevent them from bowing doesn't work well. And the 3 piece design is not set up so that the panels get any connecting support from each other. Like I said, they were popping out from just stock ballast. The shallow 1/2" aluminum channel on the floor the fit into needs to be taller too. The panels bowed and the bottoms would always pop out of it.https://uploads.tapatalk-cdn.com/202...1a4aed99fa.jpg
