I have a Honda City 2001 EXIS automatic. The problem I have is that my car feels unstable at pretty mid to high speeds. It feels like the car is floating or swaying on any side, not one specific side. This happens when I move over 80Km/h, till 80Km/h everything feels fine, but after that it feels like suddenly car has lesser grip over road and will sway.
The things that are already fine are:
Alignment: Camber, Caster, Toe everything is aligned and perfect.
Wheels are balanced. Tyre pressure is equal. Plus I can't hear any noises from suspension and suspension response is pretty soft over bumps.
What could be the issue?
