Steering rack clamps. Rubbers needed?

[Shorty]

Just been having a look on rally design website and noticed that their alloy steering rack clamps state that rubbers are not needed.

"Designed to solid mount the Escort racks without use of any bushes."

Are these suitable for the roadster? as I remember reading in the book that it states make sure you get the rubber mounts.
