It's the side mounts that transmit the most vibes. I had those in Vibratechnics as well (fast road flavour), but swiftly removed them in favour of fresh standard ones, which to be fair works well enough for most peeps with the VT dogbone. All 3 uprated is really horrible for a daily driver imo.
I think when folk buy a GTI on the original mounts, they assume that's how bad they are standard and go from one extreme to the other, but I'd recommend trying new standards first before going uprated as they are a lot better than knackered old ones.
