Description
Suspension for Easy Drifting.
・We have developed a new suspension for the concept of "smooth and moving suspension" with professional driver Nobuteru Taniguchi .
・We have set the front turning, rear traction and quick turn response with caution.
・Tested with radial tires.
・We have moved the hole position of bracket a little to have more camber angle for front (about 2 degree).
・2 way pillow upper is standard equipment.
● About installation modification
・Needs an hole for rear damping adjustment cable (inside).

*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.
