TRD have this cool rear aero stabilizer.
But... they're not cheap. They're around $175~$250 (depends on where you buy it). SuperTom made an alternative option. Using universal fender rubber cover.
It's kinda hard to see it, but it's not that thick.
Got 1.5m long, so had to cut it to the length that I need.
Here's how it looks after installing them.
Of course, it's not perfect looking. If you look closly, you can see the cut line at the edge.
