I had just installed these and they are great. you can really feel your motor and it gets more power to the ground. It rattles everthing and i know that motors do not like vibrations. Does anyone know if these are significantly bad for the longevity of a motor.

 

I got billet aluminum cradle bushings which i made and they are alot stiffer then poly and i have had no probs with my engine. So i imagine if i had no prob with billet aluminum bushings im sure your engine will be fine with poly. Also got poly bushings for my suspension all around and they are great no probs

 

i have an auto and i think these mounts are great. i notice things like the trans. not jerking when i take off after slowing down to about 10mph and the less wheel hop while doing burnouts at the track.

 

im ghetto and crazy... so im just gonna take an old tire... cut it up... dump the peices in a small pot... heat it up till the rubber starts to melt and pour it in the spaces between the mounts... let dry... and see how it goes... (BTW.... anyone ever try this... or am i the only nut in here)

 

do it, that sounds bad ***.....but use an old pot.....its gonna stink too, dont do it in yer kitchen....
