Is that the pirtek branded stuff that comes in a two sachet kind of pack?
I really don't know where the problem is. Some people use the QFM pads with no noise. I used to get noise from all 4's. After fitting in some of those Project Mu shims up front, I now only get noise from my rear passenger side. My wheel is spinning true and perfect, Ive put that red stuff everywhere I can, the grease stuff on all metal to metal points and still I get noise. It is certainly no where near as bad as before, its MUCH MUCH less now but it still happens.
