*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 long-awaited "Hipermax R" is now available for the FD2. Our latest theory has been applied to its tuning.
- To achieve unprecedented levels of both driving performance and ride comfort, SRF (Super Response Fluid) and LVS (Low Vibration Spring) have been newly adopted.
- The newly designed slide pillow upper mount and high-camber bracket in the front allow a wide range of settings, from street use to hardcore circuit driving.
(*Reference camber adjustment range: approx. -1°40' to -5°10'; default factory camber: approx. -2°40'*)
- Development was carried out on the main course of Fuji Speedway using ADVAN A052 tires. The recommended initial dial setting is 10 clicks to the front and 10 clicks to the rear. Please use this as a reference when making your adjustments.
- Tightening the rear dial beyond 10 clicks increases oversteer during turn-in and makes controlling the car more difficult. Please adjust with caution.
- For users focused on lap times, we recommend increasing the spring rate. Raising the rate to 16 kg/mm front and rear can improve times, but it also narrows the sweet spot of the suspention and makes the car more difficult to control.
- If your priority is street ride comfort, we recommend reducing the spring rate to 12 kg/mm front and rear.
- Please select the spring rate according to your vehicle specifications and intended use—for example, if your vehicle is equipped with a mechanical LSD or has different tire widths front and rear.
- We invite you to experience the evolution of HIPERMAX.
