The model in the photo is Gen2.

 

 

The long-awaited pillow ball upper mount version of the HIPERMAX S for GR Yaris Gen2 is here!

  • This new setup retains the performance of the original HIPERMAX S while adding adjustable camber capability (up to approximately 4°40’), providing greater flexibility for fine-tuning and wheel fitment.
  • It enhances ride quality and sport performance—such as roll rigidity—without compromising the refined feel of the stock suspension, making it ideal for daily driving.
  • The damping characteristics are designed to provide both smooth, supple motion and firm, controlled resistance, dramatically improving stability and control at the limit.
  • Unlike the previous version, this setup features dedicated tuning tailored to the handling characteristics of the post-minor-change (Gen2) model.
  • Testing was also conducted with the newly introduced automatic transmission variant, ensuring optimal ride quality for both MT and AT models.

*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.
