*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
・ Resetting of the stroke and damping force improve the ride quality and stability.
・ The bracket, outer, and cylinder are PNE coated for better durability.
・ Reducing the body roll generated by a stock suspension enables to improve cornering performance and delivers supple damping feeling and handling.
・ 30-step damping force adjustable steps is able to provide supple to sporty ride feeling.
・ Moderate control response and natural driving feeling do not make a driver tired even when driving a long distance.
・ Do not shorten the front case length less than 326mm since the vehicle body may come in contact with the stabilizer at full bump, and if the length is less than 380mm, the stabilizer may come in contact with the lower arm at full rebound.
・ Do not shorten the front case length less than 373mm since the wheel speed sensor connector may come in contact with the torsion beam.
※The vehicle height may not become the height shown in the vehicle information. It may vary depending on the vehicle’s individual difference.
