Pretty interesting:
Suspension Walkaround: 2012 Porsche 911 Carrera S
Changing pads at the track is gonna be a little more time consuming.
That said, 6 pot calipers on a factory setup are a nice feature.
Thanks for posting. Very informative write-up and illustration by Inside Line of all those wonderful suspension bits.
Interesting that there is another version of the 6-piston from caliper now.
I would've expected Porsche to use the front caliper from the current GT3 which is also a 6-piston unit but with a removable bridge so that you can pull the pads out without too much work...
For Porsche to change the caliper must mean that the current 6pot caliper wasnt up to snuff in some way. I haven't followed gt3's closely but have they had problems with theirs? Obviously the new caliper is less prone to flexing which should mean more even pressures and more even pad wear as well as a greater heat sink but I didn't know any of those items were an issue before but maybe they were? If the 911 is growing in weight then perhaps that's part of the reason why to beef up the brakes. Or maybe Porsche doesn't want the cars going to the track anymore so they made it harder to change pads!

This thread is very timely as I was just in a Porsche dealer lot and did a double take when I saw how big the callipers on the 997.2 GT3 were! I never knew there were that big. This thread confirms it. I thought someone had thrown Cayenne callipers on, but those are even bigger.
The front calipers were definitely updated between the 997.1 and 997.2 GT3 but not sure of the technical details.
No reports of any issues with either front caliper. Rears have a habit of overheating and eating pads due to PSM. 997.2 have some better cooling ducts to help.
Just by external appearances it would see that the Cayennes and Panameras share the brake hardware. Sheesh, between all the cars (non-S, S, turbo, 987, 991, etc), how many different brakes does the factory stock?
