For a DD the Posi-Quiets will be fine. I got them with my Z1 upgrade and they've held up to everything I've thrown at them. Quick stop braking, high speed deceleration, spirited cruises, no fading or excessive dust. In fact, they are very low dusting pads.
The only consideration, and it doesn't even impact you based on location, is when it is Really cold out, they will squeal for the first hundred braking feet or so till you get them warmed up. Other than that, zero complaints.
I'm getting ready to replace them though with Ferodo DS2500 pads for more cruises and tracking.
