*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
Aimed to provide an enjoyable sporty drive feeling especially on winding roads or high-way, it is also designed to ensure the comfortability in daily use.
The front camber angle can be adjusted to reduce the understeering.
FK7 is a vehicle with design difficult to ensure plenty of stroke amount. HKS selects our traditional single tube inverted type with a new structure to ensure the stroke amount instead of using full shock body length adjustment, focusing on the driving performance.
Front has an upper plate for adjusting the camber angle, positioning bolts are included. Upper plate installed at stock position allows camber angle adjustment ±0.5 degree.
Including an adjustment cable of the rear as a default allows an easy damping force adjustment without jacking-up the vehicle or removing dampers. The straight type spring is used allowing to easily change spring rate.
If the user prefers the front height setting higher than the default, changing the spring length to 170mm allows the height adjustment within +6 to +16mm.
Removing stock suspension requires work with front knuckle and Hub Assy. We recommend performing installation by automotive professionals only.
