The Hipermax S is a full-length adjustable coilover kit built on a monotube damper with 30 steps of damping force adjustment at every corner, using an inverted front strut and an upright rear damper on this chassis. HKS sets the full kit at 9.0 kgf/mm in front and 7.0 kgf/mm at the rear on barrel-wound front springs, with helper springs at all four corners. Shock body length adjustment covers stock ride height down to 41 mm lower in front and 62 mm lower at the rear, so corner balance is set independently of spring preload. Reinforced rubber upper mounts are fitted front and rear, and the kit carries HKS Dual PVS valving, the WR Needle soft-range damping circuit, Advanced Bump Rubber and PNE corrosion-resistant plating.
