HKS Hipermax IV GT Z34 Full Kit
This damper is for city drive with comfort. The riding quality and traction improved greatly by giving more rear stroke. We have set it least damping force for the most smooth suspension system. It will have great driving feeling because we eliminated the floating feeling or thrust. Recommended dial setting is F:12 & R:15 Factory setting has low down width because stock vehicle has the lowest vehicle height from the ground. And still it doesn't have stock high center of gravity feeling and feel great without roll. The vehicle height data from other than the test is computational data.(The numbers does not guaranteeing the height)

*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).
