• 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.
