looks to be a fair bit of meat on them. Are they worn equally on both sides of each pad? if not, replace. If they are performing poorly compared to how they used to, replace. Otherwise i think they should be ok.
sure this wasnt just a thread to show off your camera?
those pads are fine...
before the track day it would be worth taking them out and seeing if they are at all glazed.. if so (or even if not!) give them a rub on some medium-grade concrete or sand paper till they look dull and rough (as opposed to shiney)... they will feel brand new again
if your going to kill a bronze, you gotta do it BIG!
