*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
This coilover upgrades existing line-up damping force characteristics with the latest technology based on the HIPERMAX IV GT. Even with stiff springs, HKS achieves both great handling performance and ride comfort with a new damping force tuning method.
The product suits for various driving scenes as never before.
For users who prefer the ride comfort most, click the dial around 30 clicks counter-clockwise to loosen the damping force.
Feel the flexible ride and comfort with the perfect balance, however, it won't be soft too much when accelerating.
We recommend for the winding users click the dial around 15 clicks from the stiffest setting.
For circuit driving users click the dial around 10 clicks from the stiffest setting.
A stiff damping force setting without excessive firm feeling and it brings the best balance for both comfortable riding and driving performance.
The vehicle height data except test time came from the calculated value.
This does not mean that the actual vehicle height becomes the same.
● Required modifications when installing the product
A hole drilling for the rear damping force adjusting dial is required. (at a rear interior)
