I'm sure it's a fine product in the end though just don't try to make it something it's not.
One note...even if the inner seals look OK I'd suggest replacing them, mine weren't leaking or showing any issues but they had become quite hard from age and heat cycles and it was def. time for them to be replaced when I rebuilt mine a couple seasons ago.

Agreed. If they had any thermal data showing the piston actually reduced heat at the fluid, then sure, market away. I feel the same way about titanium brake pad shields. I get that an insulator can increase the time it takes for the heat to transfer, but if the piston still gets to max temp, it's not changing much.

Facts are; Porsche’s ceramic puck will crack and disintegrate. RB are solid metal.
Also, you need too heat the piston and use mechanical vice and glue to secure the ceramic pucks.
If rebuild, I would recommend solid and not use ceramics. I rebuilt using solid metal.

Lot of opinions out there. In 7 seasons and 200+ hard track days I've never broken a single ceramic puck. I believe the key to longevity is to keep the pucks firmly secured to the pistons via the Motorsport puck retainers. I have these on each piston. These retainers firmly connect the pucks to the pistons and do not allow the pucks to move around once the glue breaks down. Without the retainers, the puck can fall out during pad changes or stuff can get caught between the puck and the piston once it's dislodged and this will cause the puck to not square up perfectly with the piston thus leading to cracking. I would bet that the guys that are cracking pucks are not using the PMNA retainers or don't even know they exist. Personally I wouldn't use the Taiwanese RB stuff if it was given to me for free.

Amazed to hear some of the thoughts on RB in this thread. I was led to believe they were a popular and sound choice for upgrading the calipers when it came time to rebuilding...

You can buy the ceramic parts from FVD.net or FVD.de, I think they are on your continent as well. An advantage of the ceramic is sure that the thermal conductivity is lower. The caliper or the brake system will be more stable.

search for the thread on the pads they make that will resurface and renew carbon ceramic brake rotors.

They're fine. It's a cylindrical piece of metal that get's pushed by hydraulic fluid. It's not rocket science. This reminds me of the cheap rotor debate. Some people hate the cheap ATE (and similar) rotors. But, to me, a huge chunk of metal is a huge chunk of metal. Sure, Porsche parts may be incrementally better, or lighter, or whatever, but...

Zeckhausen provides solid metal calipers pistons too.
I did did not have the ceramic retainers but after seeing how they disintegrate I won’t go back. Could have easily popped a piston which Could have resulted in a bad day......
If you go to the 991 GT thread, there is a company that provides steel/ titanium replacement for the ceramic pucks. In the 991 pistons there is a screw in the middle to retain the pucks, so easy replacement for the 991. However, not availble for 996

why not apply a ceramic/thermal barrier coating...
FWIW, stainless pistons were a common upgrade for early AL caliper 911 S's...

Questions that come to mind-
1) Is there a pedal feel difference between a ceramic puck and a stainless piston?
2) If you did use a ceramic coating on the stainless piston ends, would it hold up to the compression and vibration, or simply wear off.
3) A disintegrated puck? I need a pic of that.
