I installed my Prothane inserts and now when im in drive and stoped at a light or a stop sign it shakes violently but only when in drive i can shift it into neutral and it will be fine

 

sounds like you left something loose. There is gonna be a little more vibration, but should not be that much.

 

al i can say is. make sure the washer went to the right upper/lower mount.. they look exact the same. but slightly diff....can i asked you. how did i cut out the rubber old insert.....i wanna make a nice clean cut out....thanx. goodluck

 

My car shakes a little more with the AC on b/c of the Prothane motor mount inserts. It shouldn't be violent at all.

 

it does shake a lot thats the u pay confort for performance

 

Mine shakes in drive too at an idle. Drives my wife nuts, but owe well. I went the reds. I knew they would viberate. Since they are for race. The blacks are for street and do not viberate as bad, I've been told.

 

no we torqued the hell out of thoes nuts hmm the motor shakes i put the damn thing in drive and pull the ebrake got out and poped the hood and the whole motor is shaking and i pressed them in with a bench vise

 

How did you support the transmission and engine while you had the original motor mounts out? maybe something could be out of balance? Rubber is soft and absorbs vibrations and polyeurothane does not. I personally think something is out of balance or your transmission could be angry at you.

 

I have the race mounts as well. Mine just vibrates a bunch more at idle. It vibrates a ton more when I start out in first gear, but I knew thats what it was going to do when I got them. However when I get moving its pretty much like normal. It should just be vibration...if its doing anything more then that then it sounds like something is wrong possibly. In my opinion the race mounts were well worth it on my car.

 

thanks guys its alot smoother at idle well as smooth as you can get either way they work fine
