Has anyone had any experience in fitting polyerethene Engine Snub Mounts & Engine Torque Dampers to their car? If so was there any improvement/difference when putting the car under high load (acceleration) in the gear changes etc? I am particularily interested in this as I am planning on a turbo upgrade next year so would like to be able to apply as much smooth usable power to the wheels as possible (noting that a new clutch may also be needed). I would appreciate any information anyone has on this subject.
