HKS Coilover Kit HIPERMAX R for TOYOTA GR Yaris (XP210) 2024+

Compared to the previous model, the rear spring rate has been increased to provide high roll rigidity and stability for circuit driving with high-grip tires, and the car has been tuned to allow for bold acceleration even in high-speed corners.

With the possibility of driving to and from the circuit in mind, we paid special attention to adjusting the damping force to SOFT, so that high-rate jolts and vibrations can be suppressed.

We tested the car on the main course of Fuji Speedway with ADVAN A052 265/35-18 tires. Good results were obtained with a front camber of -4°40', front and rear toe out of 1.9mm, and damping force dials set to 7 steps for the front and 6 steps for the rear. Please use this as a reference when adjusting your settings.

*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.
