Aerodynamic & Brake System for Skyline R34

The Brake
The Skyline offers one of the world’s most sophisticated brake systems. The Brembo brake system features race-ABS and consists of 300mm ventilated discs with 4-piston calipers up front and 280mm discs with 2-piston calipers in the rear.
Brake Cooling is improved by large ducts in the front spoiler to channel air to the front brake discs. Additionally, the front-undertray creates a low-pressure area outside the wheels, to draw the heated air away from the brakes, thus improving their cooling.

The Aerodynamics
The R34 GT-R V-Spec's (and only the V-Spec's) aerodynamics are dominated by a front diffuser and a carbonfiber rear diffuser. These regulate the airflow along the car's underbody, thus creating downforce which pulls the car down on the road. This leads to improved handling and stability especially at speeds in excess of 50mph, but also enhances stability during cornering and braking. Aerodynamics on all GT-R's are further improved by a new rear wing. TheR33’s single-wing design has been dropped in favor of a dual-level type wing on the new version. The R34’s rear wing now features a stiff main-wing with a flap that can be adjusted in four angles.
