I just got my front brakemotive setup warrantied. I think I glazed them very early on and eventually warped them. Technically not warped, but uneven pad buildup yadda yadda. I might go back to duralast gold pads instead, they were good all around and got really grippy once they got heat in them at autox. The z16's were alright for daily driving, but really really bad the first time you hit the brakes when cruising on the parkway in freezing rain. Never encountered that scenario with the duralasts but I would imagine most ceramics are similar.
I recently read that the duralast golds and bendix ct-3 are GG rated (if anyone is unfamiliar all pads are required to be stamped with cold/hot coefficient of friction and fade info) which is the same zone as hawk HP+. That rating doesn't mean everything, but gives an idea. I thought this was interesting also:
