*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.

With a stock suspension, vibration and/or flapping may be felt through the vehicle body or steering wheel when a vehicle goes over a bump or a step on a road surface.
The ride comfort may be worse if larger tires and wheels are used with the stock suspension; the impact from a step on a road surface may be stronger, the vehicle vibration may be worse, and the body roll speed may be faster due to the mismatch between the vehicle body and tires' performance.
This product was designed to improve the riding comfort while maintaining the factory good driving settings so the best comfortable performance is obtained.
Not only the high quality riding comfort by reducing the vibration and flapping of a vehicle and impact from a bump or a step on a road surface, but also total performance improvement including stable high speed driving by providing better road surface follow-up property was focused on to design this product.
This product matching was tested using a standard model and Spada under various conditions such as single to full of passengers, etc.
Stock suspension setup was designed with strong understeer. HKS have selected to deliver a setup with slight understeer for a natural handling feeling.
Direct coiling barrel-shaped springs (I.D. 65mm) are utilized for the rear side. The spring rate change is available.
The rear lower limit adjustment value was measured after removing the ride height adjuster.
●Modification for installation
A part of the rear stock bump rubber must be removed.
