*1. Height from the road surface to the fender arch.
*2. The vehicle height at the time of shipment is a reference measurement data based on the combination of the full kit settings made by HKS in-house. (This is our recommended vehicle height.)
*3. Adjustable range (However, please note that driving at the lower limit in this case will not comply with safety standards.
Also, even if it is within this adjustment range, depending on the vehicle height, interference with the body, arms, etc. may occur, which may cause problems with driving. Please note
that defects such as damper oil leakage caused by using the vehicle height at an extreme lowering from the vehicle height at the time of shipment are not covered by the warranty.)
*4. The range in which it is possible to drive without interference with the body, arms, etc. (However, this may not be the case depending on changes to tire and wheel sizes, etc.)
Note) Data may vary depending on individual vehicle differences and assembly conditions.

■ Points
・Rather than simply making it common with the ZN6 86 and the new BRZ that was released earlier, we set it up in the HKS style while respecting the character of each car.
・We pursued an improvement in ride comfort by taking advantage of the benefits of using large diameter pistons and a stylish look by lowering the car, without reducing the sharp handling without delay that comes from the sharp damping rise of the OEM.
・We thoroughly pursued the initial rise of the damping, and conducted numerous tests to ensure that the damping force was firmly suppressed so that it would not harden at high speeds while maintaining the sharpness of the handling range.
・We took time to select the spring rate, and tested it by repeatedly changing it by 1K each for both the front and rear, but in order to further improve the driving comfort, we adopted a spring with 0.5K increments for the rear for the first time.
・By loosening the damping dial, the ride becomes milder, but we set it up with the intention of not causing unnecessary fluffiness. In addition, the tightening margin is firmly secured to be able to handle sports driving on winding roads and circuits, so it is a suspension that can be used in a wide range.
・The rate can be changed at the time of shipment, but the front rate increase is supported by a straight wound spring. The rear rate can be changed to 5K, 6K, 7K, or 8K. 5K is supported by a straight wound barrel spring.
・We apologize for the inconvenience, but when installing on an automatic transmission vehicle, the front will be lower due to the difference in vehicle weight, so please adjust the front case length based on the test data before installing. This will optimize the vehicle height balance and improve it further.
