Well I ordered the O.E.M. flex disk to see what I would get. I was told I could return them if I wasn't pleased with them. Well they came today in Febi boxes. The disk were marked with SGF and Made in Germany. After a lot more research I find out that SGF makes 90% of the flex disk made. They are OEM for 90% of the manufactures that use flex disk including Mercedes. So I think I will give them a try.
