I just fitted the bottom mount to the gearbox, as the engine hangs from the top two and this will kill the pendulum effect. At first the judder was awful, but when I undid and torqued it correctly it lost most of the judder in the cabin. It took about 70-100 miles to fully bed in and now you wouldn't now it was there. I have noticed an annoying rattle from the rear boot trim which I've tried to pad out but it can be fixed and still needs some work done. but overall a worthwhile mod.
Not sure the full kit would add much as I don't get the gear change improvement being a DSG.
