Ceramic? - No....those are just the normal R35 Brakes. The R35 uses conventional materials. Full-floating two-piece rotors, The outer rotor is cast iron and the hub is aluminum. The pads are also conventional materials.
You'll find the R35 brakes on the Version S (Sport) and the Nismo (when it comes)
It absolutely will not have carbon ceramic brakes lol. Putting brakes that cost 1/4 of the car would be a horrible idea. And the leaked production cars already confirmed it'll be getting the same 4 piston Akebonos that the current 370Z uses.
