Although my situation is different from yours, I too, have had trouble getting PFC to respond to emails and phone calls - I've been tying to get dimensions of the front and rear BBK profiles so I can, with confidence, get a set of custom built Forgeline wheels
My comments were more of a general statement about my experience with PFC and not at all directed at you. Also wanted to make sure people who just purchased, or are considering purchasing, their BBK don't think they made a bad choice and wasted a lot of money.
It's clear to me based on your comments that you still want to use their products and are just looking for basic technical support.
BTW, my favorite pads are PF 01, 03 and 05 compounds, regardless of caliper type/brand.
