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.

R34 GTR Transmission & Suspension
The Transmission
The engine’s sportive character is aided by the 6-speed Getrag gearbox, which isa great improvement over the R33’s 5-speeder and convinces with short throws and well-defined gates. The new 6-speeder now features close ratio gearing for the first five speeds, instead of the first four speeds as seen on the R33. Like in earlier GT-R’s, power is delivered via the ATTESA-ETS (ATTESA-ETS Pro on the V-spec) AWD system to all four wheels, aided by a limited-slip differential, to ensure maximum traction in all situations.
The Suspension
Handling over the predecessors is further improved by a 50% stiffer body-structure and a sport-tuned suspension with a multilink setup at the rear and MacPherson struts with an additional link up front.
The V-Spec variant uses a stiffer setup than the standard GT-R, but common to both versions is the Super-HICAS all-wheel-steering system and anti-roll bars front and rear.
