*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
More advanced version of very famous HIPERMAX III Sport09 which supported many records in the circuit racing.
We have tested in circuit as well as the street and could have improved stability of rear which HIPERMAX III Sport09 lacked a little. Therefore rear tires have better grounding and roll stiffness which results in improved rear traction and absorption at a high speed driving. Once you experience the new MAX IV SP, we are sure that you can feel the difference from the Sport09.
However we also set for a comfortable ride in the street.
MAX IV SP is the perfect for the circuit and high speed driving.
