I bought the Replacement Diaphragms from Ron (JJCustomInterior) off his website ,and was a little hesitant also,but he sent them promptly after I bought them for my Helios Recaros. They are really great quality so I am glad I got them from him. The only other option is this place in the UK that is ok to deal with I have heard ,but very expensive to get stuff from them. Plus if you get the stuff from Ron you are supporting the VW community here. The stock Diaphragms are very good quality ,but that is all you can get from the place in the UK. I think the ones Ron sells (makes) are a lot better. At least, that is my impression from installing them in my GLI. I got pics of them in my repair thread that I made last year.
If you have Trophy Recaros then they will be Gray diagonal slashed kindof cloth material on the centers and Black vinyl on the bolsters. They will also have remove able power bases (or should).
