I can feel that the whole car vibrates ALOT beyond 6000rpms..

I have a stroked 2.3L motor with balance shafts removed...

Anyone experience this too??

I regret changing my mounts.. and now that my stock mount is broken, I can't replace it to stock! Sucks..

Anyone has the stock piece in good condition???

I hated mine so I traded someone on the board for their stock one.

Funny thing i was the first to have the front PowerFlex Mount at Forge and had a tad of Vib's from the Wheel but nothing more then that, Then i put in the two side mounts and all the Vib's were to the point the day i bought the car NEW.

^ lol... uhh why not just take them out?

I just have the front Powerflex. At first I could feel a little rattle, but now it's 99% gone. Feels just like stock.

However, at certain idle speeds, you'd think the dash was going to pop out.

I have the same experience with the Ralliart frount mount. I do get a bit more engine noise in the passenger compartment too.

My front Powerflex mount rattles my interior at idle. It does get to be annoying at times. I may re-install a stock mount eventually.

my WHOLE car rattles like crazy past 5800 rpms..
I dont have this when I still have the stock bushings..
I guess this mount is just too hard for my motor since it has no balance shaft..
you have to ride in my car, and you will hate it I guarantee..
this is not the regular vibration or anything near that..
this is like regular vibration times 20 or more times..
the car feels like it's going to break!

I guess no one of you has ever had the same experience as I do..
no balance shaft, big turbo, cams, + powerflex..
it's bad... not bad at low rpms.. but at 5800 to redline.. oh man...
anyone has the stock one for sale???????
