The all-new Hipermax Racing Sport (RS) coilover suspension kits are the first Hipermax line to be engineered as a truly global suspension system.

HKS suspension engineers’ spent over a year developing the Hipermax RS, testing on various race tracks throughout the world, auto cross events and street testing in both Japan and the United States.

The result of all this testing and development is a coilover suspension system that has been precisely valved to dramatically improve handling at a competitive track level, yet still be comfortable even on the harsh road conditions in the United States.

HKS was able to achieve this versatility by using an F1 inspired single tube structure coupled with an oversized piston and dual oil and gas chambers. A shortened cylinder body allows suspension travel to be maintained when the car is lowered. The Hipermax RS also features HKS’ trademark 30-way dampening and rebound adjustability that is adjusted simultaneously for easy tuning. The included anodized aluminum upper pillowball mounts improve steering response, traction and offer a more direct feel to the driving surface. On certain applications camber can be adjusted on the upper pillowball mounts. All HKS Hipermax RS coilover suspension kits are built in-house at HKS Headquarters in Japan.
