*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
Newly developed as a 20 SPEC for HONDA S660 by using the latest know-how.
Ensured the higher balance both sports and comfortability by revising damping force characteristics and using a new shaped needle and preload valve.
Reducing the damping force at the bump side leads to a comfortable ride and soft setting at low to mid-speed brings prompt steer response.
GT20 SPEC has a more damping force adjusting range compared to MAXIV GT. It makes easier to select suitable damping force in various situations.
Improved easy adjustment using rubber sheet at the front and insulator at the rear, and improved smooth spring movement.
By adding a 4 mm spherical collar helps to prevent issues with height adjustment that doesn't have enough stroke amount and also helps to avoid problems with meeting the vehicle inspection requirements.
Overall length is 4 mm higher than during our test time due to a 4 mm spherical collar that is installed as a standard at the time of shipment. Removing the spherical collar allows to lower vehicle for 4 mm.
Overall length upper/lower limits are with included/excluded 4mm spherical collar respectively.
Removing the spherical collar allows to lower the vehicle for 4 mm without changing stroke amount. Do not remove a 10 mm spherical collar. Removing it will lead to upper mount interference and may cause damage and accident.
