*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. |

| Point |
| ・The high rating MAXⅣSP for Z33 is also available for Z34 now. This suspension kit is designed for high-grip radial tires which can be used on circuits. ・It is common to use a specially shaped spring for separated suspension. Consider of changing the spring rates in this sports suspension kit. The retainer type for straight coil spring in MAXⅣSP Z33 is used in this set up. Suitable damper setting reduces unnecessary movement in sports use, which also improves drivability and creates more grips on tires with fast response in cornering. Smooth and firmly feeling is defined in this set up. By adjusting the damper softer, it eliminates the stiffness for daily uses. Also, it absorbs the shock from upthrusts to an acceptable level on normal streets. Recommended dial setting for circuit is 0~10, winding road and high speed is 10~20, normal street is 20~30. For those who are aiming for driving at international class circuits, it is recommended to give up the ride comfort and upgrade the spring rate by 2mm/kg to be more steady. High-grip radial tires are used in the test circuit. We recommend to install the size that is matching the stock tire outer diameter. Also, enhancing the water and oil cooling system and installing the LSD are recommended. ●Required Modification for Installation Vehicle's interior modification is required to install the adjustment dial for rear damping force. |
Single Tube Damper Design
Mono tube dampers allow for more accurate and stable control and adjustment of dampening. Lower ride height and center of gravity gives a more stable ride.
Dust Boot
Protect the shaft from the flying stones.
PNE Coating
Using this special surface coating provides 5 times better durability over standard galvanising. This prevents build-up around the threads of the adjustment areas allowing for easier height adjustment.
M Shaft (Φ46 normal type)
With the new design of cylinder shaft since the HIPERMAX M-1, MAX IV increased the cylinder shaft size to have a firm damping even at a little stroke range by optimizing the oil pressure characteristic. We mainly adopted this to the rear damper that can have a better driving experience.
Adopted Pillow Ball Upper Mount
For more accurate and sharp steering.
New Design Needle
Newly designed needle has been used to revise the very low speed and middle and high speed dampening which is key to a comfort ride.
Reduction of Unsprung Weight
In order to reduce unsprung weight, bracket, ride height adjusters and lock nuts are made from aluminium. (Not for all vehicles)
30 Step Damping Force Adjustment
30 levels of dampening adjustment allow fine tune adjustment for street, circuit winding roads, highway, or the weight of the vehicle.
Recently, a lot of high performance cars feature electronic control of damping force adjustment. HKS assumed it would be best to keep stock electronic control system but add an additional flexibility and offers a height adjustable spring. HKS height adjustable springs kits are a great alternative to conventional springs. With included high adjuster it is possible to select different height suiting your car and enjoy more sporty ride.
In October 1973, two talented and spirited young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not or would not produce.
Led by Hiroyuki Hasegawa, a former engineer for Yamaha Motor Company, and his partner Mr.Kitagawa, the two secured a capital infusion from Sigma Automotive Co., Ltd. (hence the name “HKS ”), and began tuning gasoline powered engines in a dairy-farming shed at the foot of Mount Fuji in Japan.
A year later, Mr. Hasegawa designed and built the first aftermarket turbocharger for passenger cars and has never looked back.
HKS pioneered the Japanese aftermarket performance industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back fuel computers and sophisticated fuel management tools. Clearly HKS was Driving Performance trends for Japanese vehicles.
Since its beginning, HKS has been committed to providing well-integrated, reliable,and environmentally sound performance systems. Mr. Hasegawa ’s strong leadership, engineering genius, creativity and willingness to listen to customers are the pillars of the company ’s success. Monitoring consumer reaction and input on issues pertaining to material quality, external appearance, sound quality, and of course, performance, HKS stays in tune with automotive enthusiasts’ needs. Moreover, HKS’ products are designed to be user friendly for easy installation.
Today the automotive aftermarket industry is filled with start-up companies following in HKS’ footsteps. None however, can match the depth of engineering or manufacturing resources available to the talented, highly motivated and dedicated employees of HKS.
For over a quarter century HKS products have been put to the test in drag racing, road racing, rallying, and top speed trials. HKS equipped vehicles have captured numerous racing championships and hold claim to a myriad of competition records using many “off the shelf”, race proven HKS components. As a result, HKS has been synonymous with “performance” in the automotive aftermarket industry for the past 35+years.
