*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.

This product was developed under the concept "Comfort & Gratifying Handling."
Mono tube large diameter piston provides the soft and comfortable ride quality during driving on a street and highway.
No upthrust over the level difference of a road and stable vehicle movement without floating feeling can be provided like the stock suspension.
Precise damping force setting along with the increased spring rate enables to provide the required damping force to the required range; therefore, the driving comfort and handling performance are achieved together in higher levels.
This product provides a stylish low-down appearance, and its shock-body length adjustment allows precise vehicle height change and appropriate stroke setting to create a vehicle specific setting.
The default dial is set to 15; for supple ride quality, set the dial at 20 to 30. To feel the ride quality more like a European car without unwanted upthrust, tighten the dial by 3-5.
Max 4 dampers utilize analysis data and perform tests on each vehicle to determine not just spring and damper rate, but also front/rear balance and stroke for people to enjoy this product safely. The concept is to try and see things from the viewpoint of the user as much as possible.
This product has many revised and newly made internal parts and includes stabilizer to achieve high levels of comfort handling and low stance without compromising.
In refining the low speed dampening, which is the key to ride comfort and handling, also the mid to high speed dampening properties, a new needle has been developed. Improved low speed dampening gives stable dampening which allows for the supple yet stable ride. It has also allowed the mid/high speed dampening to be cut which has increased performance over bumps and ridges in the road. The adjustment dial operation has been revised to allow oil to flow better to prevent the dial from locking up at under the dial 10.
※5 Without the helper spring.
Slitting a part of rear interior may be required in order to install the rear adjustment cable. Cutting off the part of rear inner fender where the spring comes in contact with if necessary.
