I know the Evo8 seats have been done. From my understanding these are pretty much the Recaro Sport so you may be able to use the Wedge brackets for them. I would call them. One thing you may want to do to is look on the Evo forums. I know some guys have removed them and replaced with something else claiming they are not really comfortable. I have no personal experience with that but thats what I found when I searched it when I was considering them.
