I don't think so, I think the pads on the non-PP is just a different material..not sure what the difference would be, maybe one is semi-metallic and the other may be more organic. I would think the PP pads are softer, hence supposedly better stopping power. I have never liked any pads that come with a lifetime warranty (ceramic) that normally means the pads are very hard and instead of the pads wearing, they wear the rotors. Ford rotors aren't really all that great to begin with. I would rather have a softer pad that wears quicker, provides a better grip for stopping...yes, you will have to replace them sooner, but pads are intended to wear. Rather change pads then rotors. I remember when my father had a rual mail route...he did something like 588-600 daily...he had to replace brake pads/shoes about every 6 weeks! Not that that really has anything to do with anything, just depending on useage will also determine wear. Hence my wife who stays on the gas until 30 feet from a red light, has had to have new pads (and rotors) on every vehicle she's owned in about 30K miles, yet I've only had to change pads twice in over 3 vehicles and 200K miles...I've really liked the EBC pads/rotors and if you visit their website, they have some pretty cool looking rotors and pads for the SHO...still haven't heard back about 13 availability from them.
