Toyota Yaris GR 20+ MK2 HKS Hipermax IV GT 20 Spec Coilovers

While moving moist and supple, pursuing a firm and sticky damping characteristic in the back, stability and controllability in the limit range are dramatically improved.

We have tested various types of spring rates and set them to spring rates that are aimed at winding + α from city riding.

* The vehicle height is the height from the road surface to the fender arch.

* The shipping height is reference measurement data based on the combination of full kit settings within HKS. (The vehicle height is recommended by HKS.)

* Adjustable range However, please note that driving at the lower limit in this case does not conform to the safety standards.
Even within this adjustment range, depending on the vehicle height, it may interfere with the body, arm, etc., which may hinder driving.
Please note that the warranty does not cover problems such as damper oil leakage caused by extremely lowering the vehicle height from the factory height.

* A range in which the vehicle can run without interference with the body or arm.
(However, this does not apply depending on changes in tire, wheel size, etc.)

Data will change depending on individual differences and assembly conditions of the vehicle.

code No . : 80230-AT025A With a

view to use in hill climbs and mini circuits If you have any, or if you are thinking of using high grip tires, we recommend increasing the rate.

Please note that the free spring length will change for both F / R when the rate is increased (*).
The recommended dial for rate up is F: D = 15 / R: D = 13.

If you are looking at sports driving, it is recommended to swing the R toe out.
Under will be less likely to occur, and you will be able to step on the accelerator earlier when you rise from the corner.
The controllability of underover is also improved.
