11.The Brembo brake system uses fully floating 15.0-inch vented and drilled steel rotors that feature diamond-shaped inner ribs for better cooling. Monoblock calipers (six-piston front/four-piston rear) employ racing-style three-bolt structures to generate stout stopping force and avert caliper distortion.

12.The GT-R's body is composed of lightweight and advanced steels, die-cast aluminum (front suspension strut housings, front and rear suspension cross-brace members, rear-seatback support, door inners, tunnel stay), and carbon fiber (radiator core support, front of the engine bay, rear diffuser undertray). Further, the GT-R's underside-made up of, from front to rear, a polypropylene under cover, a glass-fiber sheet molding compound (SMC) under cover, a carbon SMC diffuser, and a carbon diffuser-helps achieve a 0.27 coefficient of drag.

13.Before being shipped from the Tochigi factory, the GT-R undergoes a nine-lap break-in regimen: Laps 1-3 (brake quenching), Lap 4 (brake break-in), Lap 5 (transmission break-in), Lap 6 (transmission break-in, engine boost pressure check), Lap 7 (transmission contact-sudden start), Laps 8, 9 (reducing friction of suspension).
