Good question - based on the installation method recommended by Lexus for the non-f sport spoiler, I imagine that they drilled holes in the trunk to ensure the f-sport spoiler stays put from the factory as well.

If you are attempting to remove a factory installed f-sport spoiler, expect to have to check the underside of your trunk first to see where the holes are that were drilled. I'm not a 100% sure if the drilled holes on the f-sport spoiler would match the holes needed for a non-f sport version.

I would think that if you were able to remove your f-sport spoiler, you could seal the holes if they didn't match the non f-sport version and use the "tape-only" method to install.
