Lexus gs300 2007 model
What would be the cause for vehicle to vibrate at 50km/hr- 80km/hr . Up to 40km/hr is super smooth. Vibration causes slow down acceleration and After 80km/hr vibration tends to go but damped vibration sounds still persists

Tyre is good , done wheel balancing and alignments, change the most vibration dampers. Bearing has been replaced. It's a rear wheel drive car.
Please advise.
Does the whole car shake or only the steering wheel?
Car is super smooth till 45km/hr. No vibration no jerkings.. as soon it's picks up 50km/hr. The whole car starts to vibrates. And from then acceleration reduces and it takes 3 to 4 secs to reach 80km/hr ( on a speed highway even though more gas is applied) and after 80km/hr vibration tends to fade and above 100km/hr its very minimal.
Comes back when we decelerate to 80km/hr to 45kms/hr and under 40km/hr its shows no vibration.
Even if I set nuetral gear on this speed range, same vibrations occurs.
You said the tires are balanced. I would check all 4 tires and make sure they are wear evenly.
When you say tyres are good, how old are they?
It's new , even wear, Tyre were inspected well.
Yes, tyres are new and no uneven wear
