Code No. 80300-AN010
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.

*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
MAX4GT has been reviewed and renewed to make it easier to use and more versatile.
The front rate has been increased by 1K to provide better cornering performance than before. We aim to provide a properly supple driving experience.
Both front and rear are equipped with PVS and high flow rate needle, and the synergistic effect of these two elements quickly boosts damping force in the necessary areas and cuts off the unnecessary movements. The damping force is precisely controlled to provide a stable and comfortable ride quality.
Helper springs have been equipped to the front to provide sufficient stroke on the extension side, as well as a sufficient ride height adjustment range, even the previous product had a modest down amount.
The rear damping adjustment dial used to be set on the tire side, but this time we have significantly reviewed the components and changed it to an upright type that makes it easier to adjust the damping.
By doing some interior installation, it is easier to adjust the damping adjustment directly via wires making it easier to use in different situations.
It is recommended for a wide range of users, from street driving to winding roads and track.
※While installing, we recommend that you check the condition of the front arm bushings for cracks, in order to maximize the potential of the vehicle.
