The little triangle-sized pieces you'll also need. The front has two pieces on each side as well as a bracket that you can't see that goes on the inside and connects the corners of the under tray and front bumper. The rear sides each have one piece. When you go to your dealership, ask them so see an exploded view of the fenders and rear quarter panel/wheel well. you can see the small pieces. Have them order you all of them.
