*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
The new SRF (Super Response Fluid) and LVS (Low Vibration Spring) have been adopted to achieve unprecedented levels of both driving and ride comfort.
The kit was tested with ADVAN A052 Tires(255/35R18) at Fuji Speedway Racing Course.
Althoguh the spring rate is 14 kgf/mm (F/R), harder than the HIPERMAX IV SP(F: 12 kgf/mm, R:10 kgf/mm), by making suspension supple with HKS know-hows, it improves the ride comfort on the street.
The kit has been set up as slight understeer, which makes you drive reliably and break the lap time while corning at high speed.
For those who aim for breaking the record, we recommend 2 kgf/mm rate increase on the rear.
By adjusting damper force slightly tightened, it is suitable for tracks with high-grip tires such as ADVAN A052. On the other hand, the recommended damping force is slightly loosened to enjoy the weekend driving. Please experience it!
Please note that if the rear shock body length is lower than 389 mm, the upper arm and ride height adjuster may be interference.
