I posted this in the GT3 forum, on second thought it might be better suited here:

Would you say you're more pucked in the rear?

The 991.2 GT3's are still using the same calipers as the 991.1s and with them ceramic pucks. However, they have made a minute change to the actual puck design as they did from 997 to 991. In an attempt to help prevent initial cracking/chipping, they sacrificed a larger contact area for more tapered edge with a smaller contact area. As these cars have only been out for a very short time, no 991.2 has had much track use to cause a failure yet. That being said, it is conclusive by the failure rate on the 997s and 991s that the ceramic pucks have a propensity to fail on these cars regardless of the design. We will continue installing our titanium piston puck replacements as a preemptive measure on the 991.2s we have coming through the shop. Time will tell as these cars see more and more track time how the new design fairs.
