Have a search re engine mounts, i think previos advice was to use a G60 spec rear and a 1.3 spec front and gerbox mount- as these are the solid rubber ones. some of the GTi ones have hydo dampers, which can fail, and are more expensive to buy. Whatever you fit as a new standard item it'll be loads better than nackered old ones.
I fitted a couple of vidratechnics mounts to my car, initially to help with clearance for an exhaust manifold, but I prefer the standard for general driving. There is a bit more buzz/vibration and noise from the firmer mounts and I culdnt really see any performance benefit over a new standard item, which is about a tenth of the price!
