C/C and C/SiC work in completely different manners. C/C rapidly converts the kinetic energy and ablates the material to remove the heat. C/SiC has a very hard surface that the brake pads create a friction layer on and can withstand some very hot temperatures (>3000 degrees).

During braking, torque is transmitted from the disc to the bell through a fastener called a bobbin. This type of mounting system is designed to allow a specific amount of float in both radial and axial directions. This allows the disc to expand and contract under high temperature which reduces stress and increases longevity of the related components.
In this case, its not really going to be the disc expanding...primarily the the aluminum bell taking on heat from the disc.

Stainless Steel Brake Lines
Each Brembo GT kit includes a set of stainless steel brake lines manufactured by Goodridge. Goodridge is the leading line supplier to OE manufacturers and championship winning race teams worldwide. With the tightest bend radius in the industry and the lowest rate of expansion, you can be assured that every inch of pressure from the pedal is transfered directly to where it counts - the caliper. Goodridge is the only brake hose system approved for use in every country in the world and it's guaranteed for life.

Goodridge High Performance Brakeline race-bred street brake lines are constructed from the finest quality hose, consisting of a PTFE inner hose covered by braided stainless steel. In addition to providing a more responsive and firm brake pedal by eliminating the “spongy” feel that often accompanies stock rubber brake lines, High Performance Brakelines are abrasion and corrosion resistant to stay good looking for a long time to come.
Why aren't you opting the for the top of the line Goodridge brake lines? Going for some mid-range brakelines on a top-of-the-line brake system...

That will probably be what the discs run. Expect a $1-2k more for the GT calipers on both the front and rear, each, and $3-4k for the GT-R...if you are going to get the GT-R's, get them with vented Ti pistons.
