With improved damping characteristics, durability, and aesthetics, HIPERMAX S offers the best “ride comfort” in the history of HKS suspension.
- The characteristics have been reviewed to match the RZ34, and the settings have been implemented to achieve a higher level of both ride comfort and sporty performance. The rear springs are newly designed and equipped with a special spring shape that matches the new model.
- While keeping in mind the comfort of the original, we have pursued the handling performance required of a sports car to the fullest extent possible, resulting in a ride that allows for a wide control range and makes driving safe and enjoyable.
- The damping adjustment dial has a wide range of adjustment, so you can loosen it to ensure comfort, or tighten it up a bit to enjoy sporty driving on the circuit.
- By reviewing the internal components, we have achieved high durability with a 3-year/60,000km warranty.

*1. Height from the road surface to the fender arch.
*2. The vehicle height at the time of shipment is a reference measurement data based on the combination of the full kit settings made by HKS in-house. (This is our recommended vehicle height.)
*3. Adjustable range (However, please note that driving at the lower limit in this case will not comply with safety standards.
Also, even if it is within this adjustment range, depending on the vehicle height, interference with the body, arms, etc. may occur, which may cause problems with driving. Please note
that defects such as damper oil leakage caused by using the vehicle height at an extreme lowering from the vehicle height at the time of shipment are not covered by the warranty.)
*4. The range in which it is possible to drive without interference with the body, arms, etc. (However, this may not be the case depending on changes to tire and wheel sizes, etc.)
Note) Data may vary depending on individual vehicle differences and assembly conditions.

■ Points
We have set up a suspension kit with a special setting for the new Fairlady Z.
While keeping in mind the comfort of the original, we have pursued the handling performance required for a sports car to the limit, and have achieved a ride feel that allows you to enjoy driving safely with a wide control range.
The damping adjustment dial has a wide range of adjustment, so you can loosen it to ensure comfort, or tighten it a little to enjoy sports driving on the circuit.
The rear spring is a newly designed spring with a special shape that matches the new model.
To allow for development, an ID65 adjuster is used for the rear height adjustment. Although it is not covered by the warranty, it is possible to place a general-purpose straight-wound spring by combining parts used in MAXR.
Please note that if you adjust the front case length beyond the minimum length, the upper arm and body will interfere with each other.
