*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
・With this product, the floating feeling and vehicle body roll are reduced to deliver stable driving feeling that enables a driver to enjoy driving.
・L=250 spring for the front side was selected to provide better ride comfort. Replacing with a shorter spring enables to increase the vehicle height lowering range.
・Recommended Dial Position at the Test: Front – 12 / Rear - 13
・If the front case length is extended to the upper limit or larger, the lower arm comes in contact with the stabilizer at full rebound.
・For the rear side, even with factory wheels (BRIDGESTONE/ECOPIA EP150), the tire comes in contact with the fender due to the limit of vehicle side’s arm.
 
※To install this product to HFC26, adjust the rear case length to 344mm or longer from 340mm before installation.
