*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
The kit was tested with ADVAN A052 Tires(235/40R18) at Fuji Speedway Racing Course.
Spring rates are thoroughly tested. This setting allows the driver to control Civic R easily by changing its movement at their will.
Although the FK8 Civic R has a basic understeer movement, we have made settings that allow the driver to change direction as much as possible, so that the driver can feel comfortable under tracking.
Since the FK8 makes it easier to change the direction of the car by actively shifting the load, increasing the front spring rate will bring out stronger understeer movement.
The newly adopted oil makes a large range of dial adjustment, allowing the users to set the movement they like.
Even though this kit has such sport driving performance, we also pursuit the comfort which is as good as high-performance shock absorber in city driving. With just a dial adjustment, this kit can perform as urban cruiser.
For those who install size 295 in the front or A052 or higher high-grip tires, a spring rate increase from 2 kg to 4 kg in the front and 2 kg in the rear is recommended.
With stock tire wheels installed, if the front is lower than 42mm, the tires and suspension will interfere around the maximum steering angle. Please note that this will vary depending on the rim width and offset of the wheel.
(The error that appears when the stock suspension is removed can be avoided by installing an optional canceller.) ※We will be on sale.
