i've been using the project mu b-specs now for a few months
these are pretty good brake pads i must say, i don't know what you'd need to be doing to get them to fade on the street but it would need to be something pretty crazy
really good initial bite
i've been to the track with them and they were fine, though it was pissing down with rain so wouldn't have gotten up to any crazy temps
dust wise they dust up your wheels pretty heavily and they make no noise, though i did have a squeal for a couple of weeks after the track day just before the car would come to stop, but thats gone.
good pads imo
