*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.
Although the GR86 has quite good driving performance in stock condition, it still has a large amount of roll when equipped with high-grip tires, which makes it feel insufficient for track.
Respecting the original character of the GR86, we have created a setting that allows RWD-like movement and fun control of the car even with high-grip tires.
We checked the movement in track mode so that even track beginners can safely enjoy controlling vehicle.
This damper could satisfy both track beginners and advanced users who are aiming for breaking records. Even with one notch, you feel the change of movement strongly. With this kit, you can enjoy it from street driving to track.
By adopting the bump rubber that HKS has been researching for many years, it creates the stable feeling when cornering. It allows the tires to gain stable traction without suddenly losing grip.
For those aiming for breaking record, the front tires should be about 0.5-1.0mm toe out with full camber, and the rear tires should be about 0 to 0.5mm toe in. We recommend about 5 to 10 clicks of damping force adjustment at the front and rear.
For those who feel a lack of rear stability, we recommend installing adjustable aftermarket suspension arms to optimize rear camber.
