Code No. 80300-AH318
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 N-BOX+.

*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 shock generates higher roll during corning, and unstable feeling at high speeds. By adopting HIPERMAX S, it is possible to increase the sense of stability and drive comfort.
We focus the coilover on ensuring riding comfort, and this is also pursued in consideration of multiple passengers, such as family members and friends.
The most suitable spring rate has been selected to set up, leading to a comfortable riding feeling. And we also tried to avoid bouncing and unstable feeling.
Even on roads with many corners, the roll is moderately suppressed so that the vehicle can be driven stably while corning.
Do not adjust the front shock body length longer than 301 mm, otherwise this will cause interference between the stabilizer bar and the lower arm when extended.
Do not adjust the front shock body length shorter than 273 mm, the body and tie rods will be interfered at the full bump condition while corning, and the wheel speed sensor cable will be stretched.
Partial cutting of the rear spring mounting rubber is required for installation.
When you replace the front spring to 220mm, it can be adopted to further lower by 20mm from the lower limit. However, depending on conditions, this may interfere with the dust boot at full bump, so it should only be equipped when you want to lower more than 60mm from the stock.
