These fenders seem like a good aftermarket choice. What remains after replacing the rear bumper to which the rear fenders are attached? Flaps or no flaps and by law I needed flaps. So, after several weeks of searching, I decided on this set. Ease of installation. My only complaint is that they don't look like they're hanging straight, like they're hanging down a bit. I like the idea that they can be removed at any time. Will be updated if problems arise.
