Product Details
These HKS Hipermax R S660 coilovers fit the 2015-2022 Honda S660 (JW5).
HKS builds these S660 coilovers with 6 kgf/mm front and 9 kgf/mm rear springs and 30-level damping adjustment. The S660 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 coilover assemblies with spherical-bearing (pillowball) upper mounts
