An independent MacPherson-type suspension was used at the front, and a multi-link design at the rear, which provided excellent traction when cornering. Hardness springs and shock absorbers were selected in such a way that the car remained stable at high speeds.

The ATTESA (Advanced Total Traction Engineering System for All Terrain) all-wheel drive system was a real breakthrough. Under normal conditions, the car was rear-wheel drive, but when the rear wheels slipped, the electronics instantly redistributed torque to the front axle. This provided security and handling even in difficult weather conditions such as snow or rain.

Suspension model	Front axle type	Rear axle type	System Features
Standard version	McPherson	Semi-independent	Focus on comfort
GT-R (R31)	Double wishbones	Multi-link	Sports setting
ATTESA E-TS	McPherson	Multi-link	All-wheel drive with electronic control
GT-X	McPherson	Multi-link	Balance of comfort and dynamics

⚠️ Attention: When checking the suspension, pay special attention to the condition of the silent blocks of the rear control arms, as their wear can lead to changes in wheel alignment and deterioration in handling.

The steering in this model also deserves attention. Many versions were equipped with hydraulic booster, which made steering easy even when maneuvering at low speeds.
