Forward suspension bracket

Design

Independent, 4-lever, with pneumatic shock-absorbers, the adaptive damping system automatically changing rigidity of racks shock-absorbers depending on roughness of the road and clearance - depending on speed. Stabilizer of cross stability. Aluminum and steel elements are applied

Back suspension bracket

Design

Independent multilever, with pneumatic shock-absorbers, the adaptive damping system. Stabilizer of cross stability. Aluminum and steel elements are applied

Steering

Design

Rack, with the hydraulic booster, sensitive to speed. A steering column - safety, telescopic, with function of shift when landing and adjustment of an inclination
