Chassis


Body shell "lightweight and rigid"

Spot welding was added to the door frame and CFRP molded parts were adhered to areas that are easily deformed by the heat of welding to create a tough body, which serves as the frame of the vehicle. 

Special Z-tune suspension made by SACHS
Special tuning for "Z-tune" based on a damper made by SACHS (vehicle height, attenuation force, 3-way adjustment type) and which has been proven in GT500 vehicles was used for the suspension, which has a major impact on handling performance. A wide range of driving conditions is supported by mounting S tires for high-speed driving on a closed circuit to mounting sports radials for street driving.
 Damping force adjustable (3-stages), vehicle height adjustment (based on SACHS product)
 Spring constant Front: 137N / mm (14kg.f / mm)
Rear: 137N / mm (14kg.f / mm)
 Suspension link Size changing part for changing geometry
 Suspension bushing Increased rubber hardness and reduced friction

Special Z-tune brakes jointly developed with Brembo
This brake system, which was developed for a target performance of 1.6 G when mounted with S tires, was jointly developed with Brembo. It features such parts as a mono-block 6-piston caliper (for the front), 2-piece front brake rotor with a Ø365 rotor system, and Ø355 mm one-piece rear brake rotor jointly developed with KIRYU. In addition, the ABS unit was specially tuned to further utilize the performance of these high-performance parts. The ATTESA ET-S and active L.S.D. were specially tuned to accompany the increase in engine power in order to make the torque distribution to the front more suitable and to improve the rear differential effectiveness, among other things, to stay true to the great handling of the base car Skyline GT-R (BNR34).

Tires
The tires are the only contact between the vehicle and the road surface, and the tires selected are made by Bridgestone, which has provided many years of support for NISMO' s racing activities. Maximum performance for the each type of driving can be obtained by mounting the POTENZA REO1R 265/35R18 for driving on public roads, and the newly developed POTENZA RE55S 265/35R18 for sports driving on closed circuits.


Alloy Wheel "GT500 Model"
The wheel used with this wide tire is a black LM GT4 "GT500 Model" lightweight forged aluminum wheel that was newly and jointly developed with RAYS, which, like Bridgestone, has been a partner in NISMO' s racing activities for many years. A wheel with the same rim shape and color as that used for GT500 race vehicles had the rim width and offset specially resized (18 x 9.5J OFF + 5) for "Z-tune." The pursuit of thorough driving performance was extended even to the wheel.

"SUPER COPPERMIX" TWIN PLATE
The clutch is one of the major components of the power train, and here the SUPER COPPERMIX TWIN, which was newly developed to handle 441 kw (600 ps)/589 N/m (70 kg/m) and be extremely easy to use, was employed. This new clutch, which was all but developed for the NISMO R34GT-R Z-tune, uses a high-friction material made using the optimum blend of copper in the disc to reduce the friction μ and deformation caused by heat and to suppress judder, which occurs easily in clutches made of metal. Using a disc made of high-friction material makes it possible to lower the clutch cover pressing force and thus reduces the clutch pedal depression force. This emphasizes that this vehicle is a road-going car and not a racing car.

Equipped with a carbon fiber propeller shaft and differential oil cooler
The propeller shaft is made of CFRP. Weight reduction of 5.26 kg (standard shaft: 12.52 kg) was achieved to contribute to improve driving performance. The transmission and differential oil temperatures during continuous high-speed driving were optimized by installing a special oil cooler. This also contributes to realizing better stability and improving performance when driving continuously on a closed circuit.
