Product from China: Its lightweight - Stuck on via 3M d-side tape. Aesthetics purpose ONLY. Foam sponges added to the tips of the rear wing, to prevent vibration damage on car body. Enjoy!. Cheers! NB: Pls note, the wing is a universal wing. Some imaginative customisation might have to be done, to ensure a good fit. The base mounts dont conform perfectly to the contour of the car body, because they are flat. But all in all, have been driving thru sun and rain, and it has held on.
