It does not get rid of the grind...assuming you are shifting really quickly. Vibrations are at idle and also around 3500-4000RPM, but they aren't bad. I haven't had a chance to really get into any highway cruising. I thought at first something was wrong with my car. That's how weird the vibes are. But it's normal. First gear starts are really easy now. Next to no gas is needed. When I uninstalled the stock mount, I was looking over it and it puzzles me how anyone would trust this thing to hold an engine in place. Especially an engine that has 280f/lb of torque. I could literally move the mount back and forth with my hands. Biggest pile of junk. **** Mazda for giving us this POS mount. They should be ashamed of themselves. Buy this mount...you will love the difference!!!
