John, can you provide an update on your efforts to source dust boots. I am interested in the pucks, but I want all of the parts to be lined up that I will need and don't expect to reuse my dust boots. Would be nice to know who offers the high temps boots you mentioned as well as whether Porsche is making the OE boots available. I believe that RB offers dust boots (both high temp and standard), but I do not know whether they would fit your pucks. In addition, I don't know where they get their boots.
We have not yet found (nor do we know if it is possible) to source OE pistons as well. However, we have replaced a couple hundred of them at this point and have never had an issue. You just have to make sure that the piston is gripped thoroughly by a non-abrasive material. A rubber strap around the piston, pulled down tightly and gripped by a vice has been working like a charm : )
No problem, we are glad to help : ) For your reference we have had numerous GT3s/GT4s come through with the issues and took note of the variables. There is no real pattern to predict failure, the more heat cycles you have on the pucks the more likely they are to fail. We've seem them go from seemingly perfect condition pre-track day to disintegration during the event, and everything in between. Fronts fail slightly more often than rears, but the rears typically follow soon after the fronts show signs of failure if not at the same time.

New batch of piston pucks have arrived and are back in stock. Be preemptive and check your pucks to look for the warning signs, we are ready to help if needed : )

I just installed a full set of these on my GT4. It's a very straight-forward job, just a bit messy since you have to remove the calipers and pull the pistons. John gave me an excellent tip about wrapping each piston with a strap wrench and then clamping the strap in a vise (not on the piston, but just below the piston) -- this held the piston so the retaining screw could be removed without damaging the piston.
Think there's any market for the unbroken ceramic pucks? I've got 7 good rear puck and 9 good front pucks, not sure what to do with them. Any suggestions?

In regards to the factory ceramic piston pucks, there are a few things you could do with them.
1. Put tape over the holes and use them for little air hockey pucks
2. Make a little PVC launcher and use them as advanced level clay birds for trap shooting
3. Tie 100lb braided fishing line between two pucks and use it as a Bolas for hunting small game
