This is what I ran on my dual purpose E90 with PFC kit. I was running anything from AD08R, RE-71R to Cup2s and pad life and rotor life in particular were excellent. Great pads.
Cobalt friction has been sold to a new owner, hopefully they haven't changed the composition of the compounds.
Over the years, I got to know the owner who started Cobalt Friction—-super technical guy who spent a lot of time consulting for teams trackside. The pad advice I give people is the same advice he gave me. And I know who it was sold to. The new owner was trained on all the methods and has been careful with the compounds to keep things the same. The one new thing that the new owner is doing is making popular pad shapes and compounds and keeping them in stock ready to go. In the past, most things were made-to-order and there might be a wait. The AP RadiCal pad shape is kept in stock. I just ordered some a couple weeks ago and they shipped out same day.

Btw, the pad shapes for Cobalt Friction in the AP RadiCal are:
9668 or 9660 - AP19 (specify thickness)
9449 - AP13
