At any rate, do let me know how you end up liking those brakes. I may try to sweet talk my dealership into swapping out my stock pads and rotors for these ones when it comes time to replace them under warranty.
I can chime in. While I didn't change my discs when I swapped to the Performance Sport Pads, the pads have performed brilliantly. Did a track day with them
and a long road trip in the hills and mountains, and they held up perfectly without noticeable brake fade. What I especially like is the increased pedal firmness, the decrease in pedal travel and the quicker bite response compared to stock.
Downsides are the incredible amount of squeal when there isn't a layer of pad material on the discs, and yes they do dust quite a bit when they are in the abrasive temperature range. Also, they rumble over the cross drilled holes noticeably, but disappear once adhesive temperature range is achieved.
