Looks like you're due for new boots too. The cracks are pretty obvious on the center piston left side.

With the frequency of track days that you're doing, have you considered switching to the Club Racer compound? When speaking to Matt, he noted that on the track, the Club Racers will last substantially longer compared to the HC+800 (especially if you get your pads very hot).
Woah just seeing this now. It looks like those things got *seriously* hot. Thats the first HC+800 I've ever seen delaminate like that but certainly not the first time I've seen this with other pads. This is rare but it can happen from time to time if you really cook the pads beyond their optimal temp range many times over (very large heat cycles), run them down that thin and is usually exacerbated by lots of ABS intervention if you're over-braking on track quite a bit. Basically, more often than not, many extreme heat cycles make the pad material brittle and the hammering effect of ABS can cause them to break up if circumstances are extreme enough. I really only ever see this happen on very worn pads as well- typically because thats when they have the most heat cycles and theres just physically less pad material to absorb the ABS impacts.
Still would love to get some of these photos into Project Mu to see what their response is. Do you have any other data with these? Are you logging the caliper and/or rotor temps when coming off track? I know everyone wants the convenience of a dual duty pad but if this continues to happen or you find that pad life in general keeps getting worse for you with these or the MX72 then it may be time to make the jump to a full track compound for your events based on what I'm seeing.

Wait wait wait... you can't get the HC+800 pads anymore? Is that because they're back ordered or discontinued?
I have an extra set for my fronts already but my buddy (also owns an ISF) and I love these pads for street and track. Might need to grab more if they're no longer going to be available!

We were able to clean out all of Project Mu's residual inventory on these last year but are down to our last 5 sets of front and rear. Once these are gone they are truly gone.
We have three additional rear sets that are set aside for the Ferodo DS2500 front / HC+800 rear combo as well but once those are gone that will be it as well for that combo - we won't break up the 5 sets of front and rear pairs unless someone orders fronts only.
