Is highway wander caused by caster?

Without reading a bunch of stuff you've linked, or most of your post...

The Yaris has no caster adjustment. I'm betting the Corolla doesn't, either.

You can make the car track straighter with a little bit of toe-in. If you want to tinker, try adding a rear swaybar. Proper toe-in (a tenth of a degree or so... 1/16-1/8" total toe in) and a rear swaybar should give you a wander-free Yaris.

My HB tended to wader a bit on the highway but, a rear sway bar cured it.

BTW, the fist time I drove my Yaris in high croos winds, I was pleasently surprised about how stable it was considereing its configuration.
