HKS Hipermax S Coilover Full Kit - Mazda MX-5 Miata (ND5RC) / MX-5 RF (NDERC) 2015+

HKS keeps the spring rates deliberately low on the light ND platform, at 4.0 kgf/mm front and 3.0 kgf/mm rear, so the car retains its factory compliance while the damper does the work. Upright monotube units are used at both ends with 30 steps of damping force adjustment, and the left rear damper is adjusted remotely by cable. Full-length shock body adjustment covers stock ride height down to 79 mm lower in front and 55 mm lower at the rear. One part number covers the soft top ND5RC and ND5RE as well as the ND RF bodies, all on manual transmission cars.
