HKS HIPERMAX S Series Toyota MKIV Supra Coilover Kit

Part # 80300-AT010

Nine years have passed since the launch of Hipermax IV GT, and during that time we have developed new technologies. The new Hipermax S Series has all three conventional model’s characteristics and has been evolved by damping force characteristics, durability and beauty. The HIPERMAX S series offers the best ride in HKS suspension history.

HIPERMAX S Technical Features

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 influencing the driving performance.

Wide range damping force adjustment mechanism

The improved shape of the Needle jet expand the range of damping force adjustment. This makes us 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.
