Motor vibration with prothanes

[25psilaser]

Hey guys I just installed Prothanes in my laser,and i have the balance shafts removed. I knew I would have a vibration at idle, but it has a mild vibration to 8000 rpm you can hear it vibrating the car from 3000 up when i hit boost and nothing else has changed it did not vibrate like this before.Is this normal or not.

huh?

my car vibrates pretty well (think subwoofer) under 1200 RPM and above 3k its got a decent amount of vibration getting ready to go.... but more like a tweeter.

neither are terrible to me, but some other people hate them.

I don't have them but I know that Urithane is a lot stiffer than Rubber.
So Less of the Engine vibrations will be absorbed

You want to know if it's normal that you get more vibration with the balance shafts removed and prothane engine mounts?

Uh, yeah. It's normal.

Keep loose change to a minumum and the rattles won't be too bad.

I always thought prothane's wouldn't be so bad.. my friend with a GST just installed them and at idle the steering wheel feels like a massager

it's a whole diff. ride though so
