*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
Factory setting provides good ride comfort; however the original vehicle height is rather high so it causes unstable driving. This product utilizes single tube inverted strut for the front and single tube absorber for the rear side. The damping force setup was designed to securely hold the heavyweight vehicle body. Lowering the vehicle height with this product enables stylish and stable driving. Moderately lowered vehicle’s height also delivers great ride comfort on rough road surface and for family leisure. Spring rates force were determined after reviewing the result of testing under various scenes to reduce unwanted thrust feeling for better ride comfort. Product test was conducted using stock tires and 245/40-R20. For higher handling performance, increase the spring rate for the front by 1kg, which may slightly affect the ride comfort, but steering responsiveness, driving stability at high speed, and roll feeling of a vehicle will be improved. The ride height before the shipment is set to provide better ride comfort for family leisure. The ride height during the test was set for better low-stance appearance. Adjust the ride height according to a preference of a user.
