advice please

I just left for Europe with the car and got my wheels balanced before i came over but i get vibrations at high speeds, over 100kmh, just had them balanced again in France and it's still doing it, any idea what it could be? also between 80kmh and 90kmh in 5th gear the car vibrates, but it seems more like coming from the drive train

Thank you

Had same thing with the Ro. Mine was a track rod end. Had both of mine replaced. Sorted it. Could be the same thing.

Was there any change in weight, when they were rebalanced?

There used to be problems with them a few years ago, and some places just couldn't get them to balance. If it's a new tyre, it could be that it has a flat-spot.

If it's a weight problem, you can usually drive through it, and the car calms down, as you pass the harmonic point.

they were balanced last week and today. tires aren't new so shouldn't have any flat spots. the 5th gear vibration is worrying me too, its definitely a gearbox thing.... everything is Fuxxing vibrating

I had a similar problem a few years ago, and it was a track rod end. jack the car up and check by pulling the top and bottom of the front wheels for excessive play.
Also check all tyres especially on the inner tyre wall. look for any bulging of other defects, as that can throw the balance out.
Other than that from what you describe I would be looking at a gearbox mount of a prop shaft bearing.
Hope that helps.
