Sorry, we have no experience with PFC to compare . . .
There are some Rennlist Race forums that drivers talk about pads . . . you might look at those for additional information . . .
The Raybestos pads don't seem to be hard on rotor wear . . . but my son - the driver - is easy on the brakes and does a lot of trail braking to keep the car planted for turn exit acceleration . . . and we are using stock Carrera calipers . . . car is 2500# w/driver and fuel . . . we get our pads from Porterfield in LA

Just my opinion - if you have found a pad that you are comfortable with on the track and street I would stay with it until you decide to do a lot more track driving . . . then choose some pads to test over time and see what works best for you . . .because all drivers don't drive their Porsche the same way. We were fortunate that the PO had already done a lot of testing and arrived at a very good result.

Also, rotor type can make a difference in pad wear and stopping ability . . .

And, Scott - - we will see you in NorCal some day . . . we have a 94dBa Laguna muffler system too . . . came with the car and we have tested it here at a noise restricted track with sound level meters . . .
