Note: Suspension Error Canceller is included. The Spherical Bearing is a consumable. Replacement spherical bearings can be purchase separately.

Spring Rate: Front: 10.0k / Rear: 8.0k / 30 levels adjustable damping

HKS has developed a kit for FL5 that combines the popular HIPERMAX S series with a front pillow upper. It allows for camber adjustment. By increasing the tire size and camber angle, you can prevent understeer.

The three existing MAX IV GT series becomes the HIPERMAX S starting in 2021. 9 years have passed since the launch of MAX IV GT, and during that time HKS has developed new technologies. It will be a new series that has all three conventional models characteristics, and been evolved by damping force characteristics, durability, and beauty. The HIPERMAX S series offers the best ride so far in HKS suspension history.

HIPERMAX S Technical Features:

Front Pillowball Mount
The front upper mount employs the pillow ball spherical bearing. It makes it possible to change the camber angle compared to the existing rubber bearing type of the HIPERMAX S. A direct handling feeling of the car from the pillow ball top mount brings more joy to driving. It reduces unnecessary movement by improving the follow-up performance on the road surface by moving the suspension flexibly. This will provide improved ride comfort on the street.

Dual PVS
We evolved the existing preload valve system to the dual preload valve system to suppress the generation of unnecessary damping force during higher piston speeds. This provides major improvement in ride comfort without affecting the driving performance.

Wide range damping force adjustment mechanism
The improved shape of the Needle jet expands the range of damping force adjustment. This makes is possible to handle driving on a wider range of stages.

Evolution of Bump stop rubber
A new shape of bump stop rubber reduces the body roll and achieves ride comfort at the same time which cannot be achieved with general hydro bump stop rubber.

Low friction technology
With advanced tribology technology, we have achieved even higher durability and lower friction than conventional products. This technology contributes to improved ride quality and handling performance.

3-year warranty
Compared to the one-year warranty period of the conventional MAX IV GT series, the HIPERMAX S Series has a three-year warranty due to optimized internal parts and quality improvement.
