Removing the ballance shaft does not make he engine vibrate more. I did the BSD and lower poly motor mount at the same time and everything vibrated like crazy! Found out my upper mounts were bad. I changed those out and the car runs smoother than it ever has. The BSD is a cheap mod and it allows you to run an extra quart of oil. The car is not buzzy or vibrational and I drive 90 miles a day.
