*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.

Points
- The HIPERMAX R has been specially set up for the new FAIRLADY Z owners who drives on the circuit.
- By combining the increased body rigidity of the new model with the LVS(Low Vibration Spring) spring developed specifically for the HIPERMAX R, we were able to achieve both the comfort for street driving and the dampening required at the circuit, while maintaining the high rates of the coilovers that was unthinkable until now.
- The rear springs are designed to accommodate 65mm ID(Inside Diameter) straight springs, allowing for flexible adjustments to the spring rate.
- The damping adjustment dial has a wide adjustment range so that changes can be felt, making it easy to adjust to suit any situation from the street to the race circuit.
- The test was conducted at Fuji Speedway with high-grip tires, specifically the ADVAN A052 in size 275/35R19. The recommended damping settings are 8 clicks for the front and 6 clicks for the rear. Please use this as a reference when setting up your vehicle.
- The setup is designed with development potential in mind, allowing sufficient margin for adjustments such as damping, front camber, spring rate increases, and LSD installation.
- The spring rate can be changed according to your needs, as a higher rate will improve the firmness of the vehicle and a lower rate will ensure a comfortable ride.
- Circuit tests are conducted using the dimensions listed under "Vehicle Height" at the time of testing. Please pay attention to the minimum ground clearance when driving on public roads as the vehicle has a low minimum ground clearance.
- A hole needs to be drilled in the trunk interior to adjust the rear dial. Grommets are included so that the holes are not noticeable except when adjusting the dials and are usually concealed.
