drives fine. perfectly nothing out of the ordinary.
but if you put it into power mode. and go to overtake. probably dropping the auto box from 4th-2nd. it will launch from 80-120 pretty quickly (supercharged) but as soon as you ease off. the whole car vibrates. you can feel the gear lever vibrating at 4000miles an hour and the whole car shakes. is it something as simple as an out of balance tailshaft?? because as soon as you say hit a pot hole the vibrations instantly stop |

does it occur when you are not accelerating? Mine vibrates when i decelerate between 80 and 100. It is caused by the tailshaft being out of balance...so I was told.

only seems to occur when i hold gears. overtake. or drop gears.
anything that makes it rev hard and fast. the vibration keeps on happening upon decelleration aswell. but if i JAB the throttle once it goes away. almost like its stopping the revirberations. |

to me it sounds like the extension housing bush in the gearbox could be stuffed or like i said before the uni joints???

As above, plus check the rear gearbox mount, and all of the rear suspension rubbers. Let us know what it ends up being. Good luck.
