PCCB are fine with RS19, RS29, Cobalt XR1, RS15.

Has anyone used the PFC-08 on PCCB and provide some feedback?

I'm extremely surprised at how long the PFC-08 last, but given the longevity of PCCB rotors (when treated properly), this combination could be both affordable and long lasting.

PFC is harder on rotors, so might be risky to try.

RS15 is the hardest pad from Pagid. This is what the F430 Challenge uses on the front axle, I ran several of those pads, my Fiat CCB have 23 track days, front ones are fine and rear ones almost new.

PCCB are longer lasting than Fiat CCB, but no idea how PFC-08 (being an endurance compound) compares to RS15 or RS19 in regards to rotor wear. The PFC-06 seems to be more abrasive and harder on rotors per the PFC description.

I have kind of an interesting idea, a lightened 996 GT3 Cup with a 20whp increase to run TT1, TTU and DE Cup.
