Hi guys,

so recently i've noticed that my car vibrates a fair bit at certain speeds.

At 30km/h the entire car would start bouncing up and down.

At 120km/h the steering wheel will vibrate left and right a fair bit.

At 160km/h the nose of the car would bounce up and down, i can also hear things rattling.

so does anyone know what might be the cause of this vibration? aerodynamic? wheel balance/alignment? loose suspension/hub?

*note: car was tested in closed and controlled environment


Cheers
Ken
