If I did that, wouldn't the wind still push the whole thing back into the tire? Or do you mean to then hook up something (like a zip tie) to the aluminum bar and secure it to something forward of there?Get some pop rivets and thin aluminum bar stock, like 1/16th. Take the stock and make a 'skeleton' on the back side of the fender liner affixed with pop rivets. I've worked on some older luxury cars which had a hard plastic ribbing behind the liner to make sure it stayed in place, it's really common to see thicker ridges on large belly pans too. With an aluminum framework to support it, it'll be fine. Only worth it on the new one though.
