Product Details

These HKS Hipermax R GR Yaris coilovers fit the 2024+ Toyota GR Yaris (GXPA16).

HKS builds these GR Yaris coilovers with 12 kgf/mm front and 18 kgf/mm rear springs and 30-level damping adjustment. The GR Yaris is a Japan-market (JDM) car.

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 shock absorbers with spherical-bearing (pillowball) upper mounts
  • Rear springs with ride-height adjusters
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
  • PNE corrosion coating on threaded surfaces
  • 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
  • Rebuildable / serviceable construction
  • Made in Japan
