The HKS HIPERMAX S P is the evolution of the renowned street-focused HIPERMAX S, now enhanced with front camber-adjustable pillowball upper mounts for the GR Corolla. This system redefines driving comfort with a purpose, delivering a smooth, composed, and quiet ride for daily use while unlocking precise alignment tuning for enhanced grip and wheel fitment. It achieves a perfect balance—forgiving over poor roads yet providing the taut control and stylish lowering needed for spirited driving, all backed by a comprehensive 3-year / 60,000 km warranty for long-term peace of mind.

Product Overview 

Built for the driver who uses their GR Corolla 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°), providing the freedom to optimize handling or fit more aggressive wheels. It is specifically tuned to enhance the car’s versatility, covering everything from daily commutes to weekend backroad adventures.

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 noise and 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 & Style
While comfortable, the system is far from soft. It provides a meaningful increase in roll rigidity and chassis composure over stock, flattening cornering attitudes and improving stability. The included lowering (approx. -14mm F / -25mm R at shipment settings) achieves a stylish, planted stance without compromising ride quality.

🛡️ Unmatched Long-Term Support
HKS stands behind the durability of the HIPERMAX S P with a robust 3-year / 60,000 km warranty. This is complemented by full overhaul support and after-sales service, ensuring this is a long-term investment you can rely on.
