*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

Both the front and rear damping force characteristics have been

significantly reviewed and set to achieve both a higher level of ride

comfort and sport performance.

By selecting the rate that makes the best use of the high

rigidity and the combination technique of PVS and high flow needle, it

creates an exquisite damping characteristic that does not cause a

feeling of fluttering, making a ride comfort.

The effect of the PVS, that the damping force cut off at high

load, will prevent the car from bumps and will allow you to drive with

stability and feel a good ride quality.

In order to make the movement more stable, the timing of the

touch to the bump rubber, stroke volume, and even stroke amount was

reviewed and re-set to allow the driver to drive safely. 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.

Previously damping force adjustment was located on the underside

of the vehicle body, requiring time for adjustment. By cutting and

making holes in trunk interior, it is possible to adjust damping force

more quickly and easily.

A specific size grommet is included to keep the machined hole inconspicuous.
