This version of the Hipermax S replaces the rubber front upper mounts with pillow-ball units, giving a direct steering feel and repeatable camber location under load while the reinforced rubber rear mounts stay in place. The damper is a monotube design with 30 steps of damping force adjustment at every corner, inverted at the front and upright at the rear. Spring rates are 9.0 kgf/mm front and 7.0 kgf/mm rear with helper springs, and full-length shock body adjustment covers stock ride height down to 31 mm lower in front and 62 mm lower at the rear. HKS Dual PVS valving, the WR Needle soft-range circuit, Advanced Bump Rubber and PNE corrosion-resistant plating are standard.
