Code No. 80300-AH319
Going beyond just ride comfort or handling performance, a new standard of "Driving Comfort" aims for comfort in ride but also in the peace of mind generated by handling performance and drivability . An uncompromising balance which delivers on all the demands of street driving.
The model in the photo is JG1.

*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 stock damper makes high center of gravity. The deep roll angle and fast roll speed leave a scary impression of cornering. Also, driving through the bump can cause an uncomfortable shock physically, especially in the rear, which may bounce due to the light weight of the vehicle.
The concept is to create a damper that is comfortable to ride in, and how to achieve both comfort and handling without sacrificing comfort are what we pursued.
The unsafe and unstable feeling of the stock suspension is eliminated as much as possible, and the stiffness of rear coilover is also improved. While lowering the vehicle, the ride comfort is ensured.
The most suitable spring rate has been selected to set up, and especially the rear spring rate is carefully chosen by increment of 0.1 kgf/mm to improves the ride comfort while driving through the bump.
The damper eliminates the sense of bounce and moderately supports the movement of the spring, so that the spring is not stretched too much and the inside traction and tire grip are not lost. The optimal setting is made so that there is comfortable when bumping.
Steering response is precise at your will while driving so that the driver does not get tired even after long time of driving.
About modification at the time of installation
A part of the stock rear spring mounting rubber needs to be cut off.
