What I found when I had them on my car is that anti-squeal plate acts like a thin spring and pushed to pad back a bit farther than you'd get without it. This causes a bit more pedal travel to close the gap and get the pads into compression against the rotor and the result is added brake pedal travel. I liked the performance of the PFCZ pads but hated the added brake pedal travel. When I swapped them out for a set of Hawk pads the pedal travel immediately went back to normal. If I ever decide to put them back on, I'm going to peel that anti-squeal plate off them and live with any noise that may come instead of the added pedal travel.

Thank you for that information on the Z-compounds... it's nice to hear that someone else had this pedal-travel issue (and it's not caused by something I did...).
I may try to peel the backing plates off as you describe... if not, the instructor I had at yesterday's driving school seemed happy with the Cool Carbons that he used for street driving on his E46 M3, so I may try some of those.
Thanks again to all...
