*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
・Set up for driving in the circuit with high grip radial tire. For sporty drive set up dial at F-10 to 15 and R-15. For street drive set up dial at F-20 and R-20.
・We get rid of front damper’s thrust feeling at turn-in and give mild and natural steering feeling.
・When approaching corner without braking, you can control rear tire surface pressure by accelerator-off timing and adjusting to have small over steering.
・Can have traction by transferring weight to rear side from the mid RPM boost. It will have sharp acceleration without push-under by link between fast acceleration-on with not moving steering for rear kick-start.
・It has helper spring in the front and rear for it could be impossible to have enough stroke without high rate helper. Therefore they grasp the street surface for stable traction and safe braking.
・Please be careful inside rim or side wall for interfering when having big tires because the front damper spring and ride are very close to tires.
・We set the short stabilink together for front. However if you make the front case longer than 274mm, please use the stock stabilink.
・The alignment data for lower camber adjusting bolt of front strut to the maximum negative, and also upper adjustment is set to maximum negative side.
・Tire sizes are 265/35-18 high grip radial for circuit test.
