Description

The HKS HIPERMAX S P is the perfect evolution of the renowned street-focused HIPERMAX S, now enhanced with front camber-adjustable pillowball upper mounts for the GR Yaris Gen2. This system redefines “driving comfort” for performance, delivering a smooth, supple, and composed ride for daily use while unlocking precise alignment tuning for enhanced grip and wheel fitment in spirited driving. It achieves an exceptional balance—forgiving over poor roads yet providing the taut control and stability needed for winding roads and occasional track enjoyment..

Product Overview & Purpose

Built for the driver who uses their GR Yaris every day but demands more capability and style, the HIPERMAX S P prioritizes refined comfort without sacrificing performance intent. The key addition of front pillowball mounts allows for significant camber adjustment (up to approx. -4°40′), providing the freedom to optimize handling or fit more aggressive wheels. It is specifically tuned for both Manual and Automatic Gen2 models, offering the best driving experience for each.

Product Highlights

✨ Enhanced Comfort with Performance DNA
Maintains the core HIPERMAX S philosophy: a smooth, supple, and stable ride that transforms daily commutes. Damping is meticulously tuned to absorb bumps and vibrations, reducing fatigue while maintaining a sense of direct, confident control that never feels floaty or disconnected.

🔧 Front Camber Adjustment Freedom
The front pillowball upper mount is the defining upgrade. It allows for precise camber tuning to:

• Improve Cornering Grip: Optimize tire contact patch during aggressive driving.

• Accommodate Aggressive Wheels: Create clearance for wider wheels and tires.

• Customize Handling Balance: Fine-tune the car’s turn-in and mid-corner character.

🏞️ Balanced Sport Performance
While comfortable, the system is far from soft. It provides a significant increase in roll rigidity and chassis composure over stock, flattening cornering attitudes and improving stability. This “sticky” feeling inspires confidence, allowing you to carry more speed smoothly through corners.

🔄 Gen2-Specific Tuning & Wide Compatibility
Tuned from the ground up for the 2024+ Gen2 GR Yaris’s increased rigidity and character, not a carry-over from the previous model. Verified to deliver an optimal experience on both Manual (MT) and Automatic (AT) transmissions, accounting for their different weights and dynamics.

Installation & Tuning Notes

• 🔧 Professional Installation & Alignment Required
  For optimal ride quality, performance, and safety, professional installation is essential. A precision alignment is mandatory, especially to properly set the newly adjustable front camber and to dial in the proven HKS test settings (e.g., -2°30′ front camber).

• ⚙️ Dialing in Your Preference

  • For maximum comfort, start with the damping dials at the shipped setting (15 clicks) or softer.

  • For more spirited driving, adjust towards firmer settings (e.g., 10-12 clicks).

  • Use the provided ride height and alignment data as a proven starting point.

• 🛞 Wheel & Tire Considerations
  The front camber adjustment allows for more aggressive wheel fitments. However, when lowering significantly, always test for clearance to avoid tire-to-fender interference.
