Going beyond just ride comfort or handling performance, a new standard of "Driving Comfort" aims for comfort in ride but also in the peace of mind generated by handling performance and drivability . An uncompromising balance which delivers on all the demands of street driving.
Part #: 80300-AT016
The HIPERMAX S Series offers the best ride in HKS suspension history.
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-Years Manufaturer Warranty. Compared to the one-year warranty period of the conventional MAX V GT series, the HIPERMAX S Series has a three-year warranty due to the optimization of internal parts and quality improvement.

*1. Height from road surface to fender arch.
*2. Height at factory is the data tested at HKS with the setting of Full Kit. (HKS' recommended setting.)
*3. Adjustable range (However, the lowest value may not be road legal.
Even within the adjustable range, car body, arm etc. may contact. In such case, it will be hard to drive.
Damper oil leakage or any other problems caused by low ride height setting from the factory setting will void the warranty of the product.)
*4. Drivable range that there is no contact of car body or arms etc. (However, change of tire/wheel size may cause a problem.)
Caution). Actual data depends on each vehicle.
