Drove away happy with nothing felt at all on normal roads.
Back on the motorway today and above 60mph I can feel a mild vibration, 70-80mph it’s very noticeable, nothing through the steering, purely through the chassis - can feel it in the seat.
There’s no particular speed that it feels worse, it changes constantly, I find that I feel it more if I go up to speed and then let off the throttle.
I thought maybe wheels and I plan to change them anyway, so that’ll be my first job, I hoped that would fix it but reading through this I doubt that’ll be the case!

Sorry, if this was already posted. But have you checked below:
- drive shaft (also check all bolts from front to rear)
- center support bearing
- flexdisc/guibo
- transmission mounts
- differential mounts
- front subframe mounts
- rear subframe mounts
- wheels checked for dents or wobble when spinning
- put some other wheels on the car if you can
If you go off the throttle that means the load or pressure is gone from engine/drive shaft and transmission but it is still spinning under the car.
