Where's Dabear??? haha j/king.
Any how, short answer: To some, there might. If you are very sensitive to those type of stuff, you'll probably feel it. But if you feel that the mount makes the auto tranny shift smoother, then it might be worth it. Most people have noticed a slight vibration but say the good outweight the bad (slight vibration).
btw, it's brakes, not breaks. [/b]
