plastic rock guard

Today I happened to notice that an older Yaris has a plastic protector in the same area affecting the Micra. Let me see if I can dig up a pic..
Found one:
That piece is a combination drag-reducing wheel spat (the vertical part) plus a horizontal part (harder to see, it appears to just be a line in this photo) that extends forward to cover the slight flare in the rocker panel like the Micra has.
