        I should have looked closer

        my car came with the factory spoiler. the spoiler just tapes onto the back of the trunk lid, not covering any of the oem mounts. so unless I want to have 2 rear spoilers, I would have to have the holes in the trunk lid filled and the trunk lid painted. This spoiler will probably sit in my basement as a reminder to look twice purchase once.

        Speed Form Flush Mount Rear Spoiler (Unpainted)

        Had this spoiler sanded and painted by a body shop. Looks like an OEM part. Perfect. Install cost was 100.00 including painting.

        A good looking spoiler!

        This is a quality produce that was delivered almost ready for installation. All it required was some very light sanding before applying a finish coat of paint. It looks like a factory piece, on the car!

      5 Top Rated Questions

      I understand that it is recommended for the convertible, but will this fit if my s550 is not a convertible?

      • It will not. This flush mount rear spoiler is specifically designed for the convertible model.

      Why does it say for convertibles? I cant imagine why it wouldn't work on any Mustang. Mine has the spoiler delete which i initially wanted but now i want the spolier but dont want to drill holes in my trunk. Is this a good option for me?

      • The Speedform Flush Mount Rear Spoiler is only intended for use on convertible models.

      Does this spoiler clear the OEM antenna on the convertible or does it come in contact with it when the trunk is open?

      • This will not contact the OEM antenna.

      Hi what is the difference between this covertible specific spoiler and the one for the non Convertible? Would like that now looks wise etc. Thanks

      • This spoiler would be a direct bolt for the converitble Mustangs. The other would be a different size and wouldn'tbolt on properly with the convertible and would also require drilling.
