just an update on my vibration issue at speeds in the 200 Km/h range.

i had balanced the rear wheels and thought it was gone. however, sometimes it still returns. vibration in the back.

anyone else notice something like it ? any clues as to waht it can be ?

maybe i should rebalance the wheels at another shop ?

could anything else be causing this ?

as said its only there in the 200- 230 km/h range.

problem is also that its not that easy to maintain these high speed for lengthy periods to locate the exact speed zone where it occurs.

however, below these speeds everythingis fine, therefore i doubt it would be drivetrain related

 

If the problem comes and goes .. its probably due to the poor quality of the roads. If the problem always happens; then you would need to rebalance (with a proper mechanic).
