i have my own opinions here. yes i am buying them but that does not make me bias as to him getting rid of them if he doesnt want to i would just buy them from pole but i do agree that 2 stiffer mounts have to have more nvh than 2 brand new factory mounts. it maybe minimal but still more none the less. odds are if theres alot then the mounts are binding up or preloaded and will cause alot more nvh and not work correctly.
