Hi, I got solved my problem installing 3 inserts in the silentblocks of the rear diff.
034motorsport sells an insert kit, for rear diff and gearbox

Number 4 and 5 in the photo
I bought in a store in england, but I dont remember the name.
With 700nm the vibration dissapeared, but then I got 800 with upgraded turbo, and the vibration came again, but no so hard as without inserts.
also they buy aluminium silentblocks, but I though they may be uncomfortable for a car to use every day.
