Update: reading a Japanese article, I discovered that Subaru added a couple of stabilyzing spoilers behind rear wheels, on the bumper in models G and H, and suspensions have been tuned accordingly. Toyota didn't, that's why Subaru rear shocks have been revised, but not Toyota's.


Update 2: not Sachs, but these are the other OEM specific options.
