Me and kebabman discovered moons ago that if you chock the top mounts buffer the mount does not move at all!! result
Got so fed up with engine movement as I change gear and come off clutch
Even with new mount there was little change
Basically all I did was remove the top cover part of mount
Made up a piece of 4mm angle. Drilled a hole in it.
Wedged it between mount buffer and body (totally locking the mount so it can't budge)
Then bolted it down with the existing bolt that holds the cradle on
It's amazing the change it makes to the feel of the car
