Product Description
HKS Hipermax S coilovers give the Nissan 370Z a lower, more controlled stance while retaining the composure needed for regular street driving. The 30-way adjustable monotube dampers allow the response to be tailored from a more comfortable street setting to a firmer setup for canyon roads, autocross, or track use.
HKS uses its Dual Preload Valve System, wide-range damping adjustment, and vehicle-specific bump-rubber tuning to control body movement without making the Z34 unnecessarily harsh over broken pavement. The full-length design adjusts ride height independently of spring preload, allowing the car to be lowered without using preload to set the final stance.
Product Video
This official HKS video explains the HIPERMAX S series and its Flat Ride Concept, which focuses on balancing controlled handling with improved ride comfort. The video covers the Hipermax S line rather than this specific 370Z installation.
Before You Buy
This is not a true-rear conversion. The HKS kit retains the 370Z’s factory-style separate rear spring and damper layout, so bucket-delete rear toe arms are not required for installation. Once the ride height is set, have the vehicle professionally aligned. Lowered Z34s can require rear camber and toe adjustment to achieve your preferred alignment settings and maintain tire life.
