HKS Hipermax S Coilover Full Kit - Honda S2000 (AP1/AP2) 1999-2009

Both ends use an upright monotube damper with 30 steps of damping force adjustment, and the left rear damper is adjusted remotely through a cable so the dial stays reachable with the interior trim in place. HKS sets the full kit at 10.0 kgf/mm front and rear with helper springs at all four corners. Full-length shock body adjustment covers stock ride height down to 77 mm lower in front and 53 mm lower at the rear, and factory spring rate changes are available from HKS at time of order. Reinforced rubber upper mounts, Dual PVS valving, the WR Needle soft-range circuit and PNE corrosion-resistant plating are standard.
