Rear axle flex on Mirage without a sway bar

[Alemon]

As you can see in this video, I can flex the axle easily with my bare hands and it has a lot of play/movement and thats why a sway bar is highly recommended to increase the stability and safety at high speed of this car.

I recently bought a sway bar from daox to minimize the axle flex or improve the stability of my mirage.
