*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
The ride quality improvement under low speed range at a low speed and on rough road surfaces and vehicle handling stability improvement were focused when developing this product.
For this product, the inverted type strut suspension is selected for both front and rear dampers. Compared to the stock suspension, the inverted struts enhance the rigidity remarkably and support the handling stability improvement.
The offset upper mount designed specifically for S660 enables to obtain the sufficient stroke amount even after lowering a vehicle so improvement of the ride quality and vehicle handling stability is implemented together.
The front damper is not using the stock-body length adjustable system to utilize the original performance.
The spring change is available; however, the spring rate must be carefully selected since the vehicle height changes considerably depending on the spring rate.
