Yes, our *front* 6-piston calipers are similar to those found on the C-GT. The rear calipers on the Cayenne are *only* 4-piston calipers. I believe the C-GT's rotors are 380mm (14.96" in diameter) while the Cayenne has a 330mm (13.5"?) diameter.
Of course the single biggest difference is the fact that the Carrera GT uses the Ceramic Composite braking system (PCCB - Porsche Ceramic Composite Brakes) and our rotors are steel. PCCB as an after-market purchase is $13,995! And, no PCCB is not available for the Cayenne model line.
You CAN brag that your brakes are the same as those found on the stock 911 Turbo (wihtout the PCCB option).

Aren't these the same six-piston monoblocs? If so, I can brag that these are the same brakes as used on a $450K car.

If anyone uses their brakes REALLY hard occasionally, I recommend removing the stamped-steel dust shields. I have on front and their absence helps the rotors cool. Haven't on rear yet because I haven't received the set of triple-square sockets I ordered over the weekend. If you think you'll ever want to work on your C, I recommend you buy one of these http://store.yahoo.com/bradystools/3dr8pmetrsqb.html .

The fronts are easy.
This is from (not-good) memory so I don't remember all sizes.
1. Lift and safety-stand the vehicle and remove the front wheels. 2. Remove the front calipers. First remove the small (allen-head?) screw holding the brake-line bracket to the rear (inside) of the kingpin. The calipers are anchored by 2 big (normal) hex-head screws of 19mm head size (IF I remember correctly, and that's a big 'if'). Have some mechanic's or some other kind of wire handy to tie the caliper up out of the way. DO NOT let the caliper hang on the brake line. 3. Remove the rotor. It's held to the hub by a Torx-head screw. 4. Remove the 3 (10mm-hex?) screws holding the shields on and remove the shield. 5. Install the rotor, then caliper, then line bracket, then wheel.
The rears are another story and post.
