well i am planning to buy the hasport 62a street motor mounts for my car but.. i need to know if there is it stiff as hell? like will my car shake much at all? i heard if you have them in for a while about 10-25hours of engine running time they will loosen up and not be as stiff? i just don't want my car to be shaking like hell because of the engine vibration.

 

I don't know if this would help, but I'm using the driverside upper mount only and my car doesn't really "shake like hell". There is some/little vibration, but I got used to it after awhile.

 

they dont bother me, you can feel and hear the vibration every now and then though.

 

I'm running the 62A mounts. For the street, they're perfect. I honestly did not notice any more vibration over my old, stock mounts. I'm looking to bump up to 70A.
