Description

The HKS HIPERMAX S redefines the driving experience for the GR Yaris Gen2, masterfully balancing refined daily comfort with genuine sports performance. Engineered specifically for the updated platform, it transforms the hot hatch into a more sophisticated, composed, and versatile companion. By utilizing a new, reinforced rubber upper mount and Gen2-specific tuning, it delivers a smooth, supple ride that absorbs road imperfections while significantly improving roll rigidity and high-speed stability for confident, enjoyable driving on any road.

Product Overview & Purpose

Designed for the enthusiast who uses their GR Yaris daily, the HIPERMAX S prioritizes a qualitative upgrade in ride comfort and noise isolation without sacrificing handling capability. It replaces the stock suspension’s sometimes brittle feel with a damped, “sticky” composure that flatters both the driver and the road. Tuned from the ground up for both Manual and Automatic Gen2 models, it is the intelligent choice for enhanced real-world enjoyment.

Product Highlights

🛋️ Redefined Driving Comfort – Smooth & Composed
The core philosophy is a transformative improvement in ride quality. The damping profile is meticulously calibrated to be smooth and supple, effectively filtering out high-frequency vibrations and sharp impacts from poor road surfaces. This creates a quieter, more refined cabin environment and reduces driver fatigue, making every journey more enjoyable.

⚙️ Gen2-Specific Engineering with Reinforced Mounts
Not a carry-over kit. It features an HKS-designed, reinforced rubber front upper mount to accommodate the Gen2’s revised three-bolt strut tower. This mount provides a more direct response than stock while effectively isolating harsh vibrations, contributing to both improved handling feedback and cabin comfort.

🏞️ Balanced Sport Performance & Stability
Beyond comfort, the HIPERMAX S delivers a substantial performance gain. It provides a meaningful increase in roll rigidity and chassis control, flattening cornering attitudes and inspiring confidence. The result is enhanced stability during spirited driving and a more planted, secure feel at highway speeds.

🔄 Wide-Range Adjustability for Personalized Driving

• 30-Step Damping Adjustment (F/R): Easily tune the character from a plush, comfort-focused setting to a firmer, more responsive feel for backroad driving.

• Full-Length Ride Height Adjustment: Achieve your desired stylish lowering (approx. -27mm F / -26mm R at shipment settings) while maintaining proper damper stroke for performance and reliability.

Performance Philosophy

• Goal: To provide a significant, holistic upgrade in ride quality, composure, and style over the stock suspension, while retaining enough performance intent for enjoyable backroad and occasional light track use. The focus is on smoothness, refinement, and daily driving pleasure.

Installation & Tuning Notes

• 🔧 Professional Installation & Alignment Recommended
  For optimal ride quality and performance, have the system installed and aligned by a professional shop. Use the provided ride height and alignment data as a proven starting point.

• ⚠️ Critical Lowering & Clearance Notes

  • Clearance Warning: With factory wheels/tires, setting the front case length below 313mm may cause fender interference at full lock and full bump. Setting it below 301mm risks inner fender liner interference. Lower with caution and test for clearance.

  • Automatic vs. Manual: The shipped settings are optimized for AT vehicles. For MT vehicles, a slight adjustment to ride height may yield the best balance.
