yeah i seen all about that mate i made a post earlier in the year and mentioned that exact one myself but the lack of a known brand...thoughts of too good to be true put me off
i done some reading and it turns out alot of companies paint the parts red and thats about the only difference...and sometimes the parts are even worse
if ya not looking to spend much money, get a standard one...i ended up paying 160quid for a standard part (theres a thread somewhere in mk3 section if u want a read about my adventures)...vwspares offer one for 87quid delivered but it turned out to be the wrong one 220mm instead of 228mm
u should be able to source the standard one much cheaper than wot i paid, the garage that done the work for me made a tidy mark up after they quoted a pretty cheap labour
tbh i dunno much about it but iv never heard of mounting a diesel clutch up with a G60 flywheel, afaik the flywheel is not a
problem and the only reason to swap it is for the lightened/balanced types or to mount a different size clutch.
as for 'real' uprated parts i only know of helix but ur talking loads
