The way I heard it was,There is no stupid question but the one you didn't ask !!! If you look at a lot of racers,you will see either solid motor mounts (vibrate your car like crazy) or Torque staps that tie the drivers side down when you get on it !!! It's also a great way to tell if you have a broken motor mount !!!Lifts too high when you put it in gear and step on the gas slightly,or for the passenger side, put it in reverse and step on the gas slightly !!Plus it will also tell you if your tranny mount is bad !!! Hope this gives you a little more info !!
