Product Details
These HKS Hipermax R NB MX-5 Miata coilovers fit the 2001-2005 Mazda MX-5 Miata (NB).
HKS builds these NB MX-5 Miata coilovers with 12 kgf/mm front and 12 kgf/mm rear springs and 30-level damping adjustment.
The Hipermax R is HKS's flagship street and circuit coilover. It pairs single-tube dampers with HKS's Super Response Fluid and Low Vibration Springs, so the car turns in sharply, stays flat in corners and keeps consistent damping through repeated heat cycles, while still riding well enough for the drive to and from the track.
What's in the Kit
- Front coilover assemblies with spherical-bearing (pillowball) upper mounts
- Rear coilover assemblies with spherical-bearing (pillowball) upper mounts
Features
- Inverted monotube damper for strut-type applications, constant damper performance under load
- 30-level 1-Way damping adjustment dialed in via the WR Needle valve system
- Super Response Fluid (SRF): exclusive high-temperature-stable damper oil
- Low Vibration Spring (LVS): lightweight 210k-grade high-strength spring wire
- Dual Preload Valve System (Dual PVS): individually tuned per vehicle
- HIPERMAX-exclusive upper spring retainer for coaxial spring/damper alignment
- Pillowball upper mounts where applicable, zero deflection
- Length-adjustable shock body: lower ride height without pre-loading the spring

- Advanced bump rubber: progressive load response, tuned for race pace
- DURA BOOTS heat, weather, and ozone-resistant dust boots
- 2-year / 40,000 km warranty
