Centric Pads

Good call - I'm running Posi Quiets on my 991.1 C2 to replace the noisy OE pads. Initially bite is minimally diminished, overall stopping power feels the same, noticeably less dust, and not a peep. Important to note, the compound for our cars is semi-metallic, not ceramic which equates to better stopping power and slightly more dust.

Brake dust is not caused by the pad - its caused by the pad eroding the iron on the brake rotor.
"Brake Dust" is very fine particles of iron that are coating your wheels and if you think about it, it makes sense. Rotors wear. So to get less dust you use a less aggressive pad that doesn't abrade the rotor as much. HOWEVER - the tradeoff is a loss of stopping power and resistance to severe heat fade in particular. Personally I would never esmaculate my Porsche, which has some of the best brakes ever put on a production car, by putting on an under-performing pad that requires several more feet to stop the car and also is subject to heat fade in a track-type environment in the name of clean wheels. Plus soft pads wear much quicker. Clean your wheels with soap and water rather than installing an inferior brake pad.
Brake squeal is caused by high-speed oscillations of the pad (vibration) typically its the backing plate clearance in the caliper bracket. As the brakes get hot with use, that metal backer expands and fits the bracket perfectly. They only squeal when cold and the brakes are not warmed up.
Sports care are different from basic point-to-point transportation vehicles like a Mazda 3.
Don't believe the above? Well, it comes directly from Porsche - in more detail:

Agreed. To say that pads are not a major contributor to dust on the wheels is to say that the pads do not wear. Much easier to attribute wheel dust to the pads than to the rotors as iron particles should show rust on the wheels.

Here is a short article about the sources of brake dust from EBC brakes. I'd guess they know what they're talking about:

Well I'm at a loss because I have cleaned and cleaned and then heated and heated these things and they still squeal when applying very light pedal pressure. I just don't go jamming into the stop at lights or stop signs. I see a light change to red and I just coast to the light. 9/10 times I need to tap the brakes a little to keep from bumping the car in front of me and there it goes... ''ssssqqueeeeeell'.. I'm like fk...stupid brakes. Everyone's looking around at whose car is squealing..
haha.. I start looking around too - like, not me.. who is that?? hha

what is nice about the centrics are that they are self bedding - install and drive. I have had no squealing whatsoever. I think they stop better than my oems and I like them a ton better, to be honest. little disappointed with the amount of brake dust though - a lot more than I expected (or wanted)
