*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
We have set it for the mainly street use with the F SPORT type. First, we set the vehicle height low for cool look. You can adjust the damper setting because it’s a height adjustable lower bracket type. We try to keep the stock’s stroke and drive feel. But there is some rolling, and N mode and S/S+ mode has some wrongness. We adjusted for these problems and have even smoother driving experience. Also we adjusted and set the weight allotment for springs and dampers for best steering and less rolling. But still have the great feeling for human sense. We have set enough stroke as the stock to reduce the uncomfortable reaction from road surface. We also checked with electronic device for stability and comfortable drivability. Please set the dial at 15 for beginning and drive for a while. Then if you prefer more comfortable ride, set it at around D20 or set it D00 for sportier ride.
* We have checked with TRD stabilizer, so you can also use it to reduce the rolling.
* When lowering down by using special wheels, we recommend not changing factory set case length because it will interfere with front upper arm and also inner front and back stay and tire. We also advise not to use bigger front tire.
