High speed vibrations on Sag
Discussion
80+ mph, had all wheels balanced, made no difference. Can't feel where it's coming from, feels like the whole car. Not a violent vibration but irritating - remains if I declutch and coast. Seems to do it more after a hard acceleration up to these speeds but that could be in my mind.
Anyone got any ideas? Dif, prop, driveshafts?

Jappo we had a similar problem with our Sagaris.
Symptoms were the same. Turned out to be delamination of one of our rear tyres. An area of of tread was 'bubbling up' at speed.
Modern balancing machines use a static balancing system, so they don't find any distortion due to speed.
The cure to our problem was a new tyre.
The problem was hard to diagnose being at the rear. Front end balance problems are generally easily felt through the steering. Rear tend to vibrate through the whole car as was ours.
Would suggest borrowing a spider from another Sag and substituting each rear one at a time.
Hope this helps.
