Why are we comparing Vios with Wira? Vios is a new generation car with brand new chassis, unlike the 15-yo CA chassis inherited from the Japanese. In addition to that, Wira is not a competitor for Vios, it has also been discontinued, it's much cheaper and obsolete.
My whole point of my previous post was: Who says Vios is unstable at speed? Come I bring him for a run. Most of the time, it's the driver and the road..
So, OT abit, regarding Wira stability... well this was taken back in 2004, stock standard suspension, photo was taken with a stupid (retired) Fujifilm camera by a passenger sitting on standard seat, straped with standard safety belt:

I am not sure if I can call this stable or not. Not even a shake.
