*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
・Ride comfort becomes better than the original by natural movement and supple handling provided by this product.
・Lowering a gravity center provides better driving feeling without feeling its vehicle height. Lowered vehicle height brings its beautiful body line into prominence; its appearance is transformed to a sophisticated and wild sedan.
・Absorbing the uncomfortable vibration prevents fatigue even in long driving so driving becomes more fun. Ride comfort in the rear seat is also maintained.
・The spring rates were chosen to provide the best balance of the handling performance and ride comfort. Even on rough and uneven surface such as the difference in level over a railroad crossing, manhole, and street intersection, the driving performance is unaffected.
・Damping force adjustment cable for the rear side is included. Damping force is easily adjusted without removal of the suspension and/or liner of the vehicle interior.
・A large diameter piston, single tube shock absorber, and reinforced rubber upper mount are utilized to provide a high quality ride feeling that matched with the vehicle rank.
・Settings were determined after conducting tests in Shanghai, China using the vehicle available in China. The optimal damping force was selected for the conditions of the local highways and streets.
