The Hipermax S uses an upright monotube damper at both ends of the Z34 with 30 steps of damping force adjustment, shipped set to click 15 as a street baseline. HKS specifies 10.0 kgf/mm front and 9.0 kgf/mm rear springs, with a helper spring at the front, and full-length shock body adjustment covers stock ride height down to 43 mm lower at both ends. Reinforced rubber upper mounts front and rear preserve the factory noise and vibration behaviour that a pillow-ball kit gives up. Dual PVS valving, the WR Needle soft-range circuit, Advanced Bump Rubber and PNE corrosion-resistant plating are standard.
