If you have access to a ramp or even axle stands, its a 5 minute job, your local mechanic could do it for you for next to nothing

I think this will be the next thing on the to do list.
The only thing I'm a bit worried about is with the extra vibration it may make the million and one rattles my car has worse!

I doubt it would as it only happens at idle, it really isnt harsh, you just know its there

Were did you get yours mate
Were did you get yours mate
stevie, if your ever near motorscope again they fitted mine in under 10 minutes, never knew you were after one or you could have had a feel of my vibrations last sunday

Will the vibration cause long term damage to the engine, gearbox, chassis, Etc.
IMO surely the standard jobbies reduce idle vibration for a reason other than just comfort. IMO they would be ok on a track car which is used once or twice a month but for a car which is used several times a day would it be a wise decision? This is only my opinion folks,

Looking at it logically it will reduce the torsional stress on the mounts to have less movement, both compressive and extending
It should have no effect whatsoever on the chasis and in terms of the drive train well it will give more stable forces.
The only reason the original mount was so soft is to reduce vibration through the cabin
It is still nowhere near track tight, its just a little more edgy
Try one and see

With all due respect this is incorrect.
It is an empirical law of physics that energy of closed system remains constant. It is a fact that softer mount will absorb more energy by converting it to heat. Energy now unabsorbed has to be dissipated elsewhere. Some of it will be passed on to the chassis, some to top mounts and some will be used by the engine internally thus increasing useful output. How much goes where is impossible to say without taking measurements.
The harder mount does reduce amplitude of engine vibration on top mounts but it does increase the energy passed onto them. If that energy is enough to destroy them is impossible to say without testing. You could x-ray yours for structure changes before and after for definitive verdict

Very true if we were talking about a closed system, however, we are not.
The system is open in so far as the drive train now clearly takes up the the previously wasted energy evidenced by the sharper response. As for the softer mount dissipating as heat, this is not the case or if it were looking at the mount and indeed feeling it after removal the energy involved would be v v v small.
