*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.

This damper has been developed to provide high ride quality through its supple yet stable setup. Once out at the race track, a twist of the adjustment dials can provide the performance necessary to enjoy the circuit.
Max 4 dampers utilize analysis data and perform tests on each vehicle to determine not just spring and damper rate, but also front/rear balance and stroke for people to enjoy this product safely. The concept is to try and se...
