What's the simplest way for me to word this.... If your happy to try these for the £400 investment (F&R) then do it, I highly doubt you'll be disappointed. They are probably the best braking upgrade for a stock caliper I've experienced.
My only concern and I've spoken with @Deacon about this is, what will the durability be like running a high spec endurance pad on the disc's and calipers over the course of a couple of years. My BBK has been faultless over the 3 years I've had and it's not used any consumables other than when I've wanted to try different pads.
Ask me about the PFC08's again in a months time, as I should be getting a set for my BBK, to use at Spa.
