I guess its just for aesthetics. My original brake pedal cover had a hole in it and kept falling off so that is why I "upgraded" to the WRX pedals.
Compare it to installing a spoiler, splash guards, brush bar etc, neither of which would make the car faster, last longer, or ride better... but people still install them.
