OK. So I decided to give stock brakes one more shot, this time with a set of Pagid RS-19 pads. I just got a set from M-World and was reading info on pagid website and found out some interesting points. Bedding procedures is very different from what I have seen before (attached). Those who have bedded these pads before, please comment on whether you followed this procedure or some other.
This link has more very interesting facts, IMO. http://www.braketechnology.com/techinfo.html
PS. Also, I noticed that on the picture of a GT4 that I took during my visit to Welt last year, BMW installed a set of Yellow endurance compound Pagids.
