Hi all

i have a problematic Classic that shakes in the hole car under acceleration and shakes the hole car when highspeeed over 200kmt and it Will only stop shaking when you slow complete Down

i have a 6speed uk gearbox
r180 rear diff
driveshaftshop rear shafts
new front shafts
carbon propshaft without center bearing
Hks carbon twinclutch
also it have powerflex bushings in the rear T-bar and
diffmounts

the rear diff , propshaft , all shafts have been changed becourse of the shaking and i have not made Any change

Can the front diff or center diff make the car shake like this under accel , or could it maybe be a Bent gearbox input shaft ?
Or Any other suggestions ?

Any info would be appriciated

thanks
skassa
