*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

This product was developed under supervision by rally driver Mr. Toshihiro Arai. This is the ultimate suspension available for all road conditions with the stabilized road holding performance providing better ride comfort. The front and rear strokes were extended compared with MAX IV GT, and the newly developed bump rubbers act as sub-springs providing the best road holding performance in various road conditions. The damping characteristics are perfect for handling and ride quality. The spring rate is the same as MAX IV GT, and a 2kgf/mm bump rubber is utilized in a contraction side; these are for better handling and ride comfort. This product is designed to provide flat ride with supple and natural damper stroke in high quality. The front camber adjustable pillow upper mounts enable a wide range of alignment and improve integrality of the damping force.
The dial position Mr. Arai recommended for circuit driving: Drive emphasizing on FF’s characteristics: 10/7 Drive emphasizing on FR’s characteristics: 10/5
 
・The vehicle height except the tested height is the calculated value; therefore, actual height may be different.
・Drilling a hole in the rear liner for a rear adjustment cable is required.
