My track pads always wore quite evenly.
So I guess a conclusion could be that the stock calipers may not be sufficient for low torque pads when you stand on the pedal all the time? I remember having to really stand on it with the PF-Zs installed. Light as a feather with the PF-01s.
I've never heard of problems with RS-19s crumbling. I've experienced that with Hawk pads, though, and it is quite un-nerving when it happens going into a heavy braking zone
Mostly Spec VRs, and then later DTC70s. Neither faded - EVER, plenty of stopping power at all times. Both of those are pretty high torque pads, at the expense of durability. I never tried the PFCs, but I think cooling would ultimately have been the solution. The BBK I ended up with solved all the problems and gave me a very firm and consistent pedal in all conditions, though pretty much overkill.
I think I've been though 15 sets of DTC70s now between the OEM calipers and the BBK, they are pretty good pad at a value price (and very nice to rotors)
