I had them fitted to my EK4, rear engine mount and front torque mounts, and removed them after a week of daily driving. Too much vibration going through the car amm dashboard when idling and driving off for my taste. After driving off and getting some speed there was very little vibration that could be felt. Really not that annoying.
Did like the throttle response of the car. A blip on the throttle and it would just go with no delay. Must admit that if this could be had without the vibrations during idling then I probably wouldn't have removed them.
I removed the torque mount inserts first and there was some improvement regarding the vibrations. Having the rear engine mount insert would maybe work for you as it does for a mate of mine on his DC2 as the engine is still more rigid then with OEM mounts and there are less vibrations through the chassis.
I do drive my car every day and occasionally on the track so I try to delete everything from the car that annoys me and is not essential.
