Description

The HKS HIPERMAX R is the pinnacle of coilover engineering for the Nissan GT-R R35, designed to deliver unparalleled control, versatility, and feedback from circuit to challenging backroad. Incorporating groundbreaking technologies like Super Response Fluid (SRF) and Low Vibration Springs (LVS), it achieves a previously unattainable balance of razor-sharp handling and refined ride comfort. Developed and validated on Fuji Speedway with advanced tire setups, this system provides a wide, durable adjustment range and includes proven track settings, making it the definitive suspension upgrade for the driver who demands the absolute best.

Product Overview & Purpose

Built for the serious GT-R driver, the HIPERMAX R transcends traditional coilover compromises. It replaces the factory setup with a motorsport-derived philosophy focused on maximum mechanical grip, precise driver communication, and high-speed stability. The integration of exclusive new fluids and spring technology allows it to provide exceptional body control without harshness, creating a truly multi-performance suspension capable of dominating track days while remaining composed on the street.

Product Highlights

🏁 Revolutionary Core Technologies

• Super Response Fluid (SRF): A newly developed, exclusive damper fluid that provides faster piston response and more consistent damping performance across a wide temperature range, translating to more immediate and predictable handling.

• Low Vibration Springs (LVS): Exclusive high-strength springs engineered to minimize high-frequency vibration transmission to the chassis. This groundbreaking technology significantly improves ride comfort and reduces cabin noise without sacrificing spring rate or performance.

🎯 Fuji Speedway-Optimized Performance

• Proven Track Settings: Developed on Fuji Speedway with high-grip ADVAN A052 tires. HKS provides recommended damper settings (F:12, R:8 clicks) and aggressive alignment data as a turn-key baseline for circuit performance.

• Exceptional Roll & Pitch Control: High spring rates (196 N/mm F, 157 N/mm R) provide immense roll rigidity for flat cornering, late braking, and precise throttle application, essential for exploiting the GT-R’s high power and grip.

🔧 Professional-Grade Adjustability & Access

• 30-Step Damping Adjustment: Features a wide, precise adjustment range. Rear adjustment is accessible via a convenient wire without removing the damper.

• Full-Length Ride Height & Preload Adjustment: Enables precise corner balancing and optimization of center of gravity.

• Pillowball Upper Mounts (F/R): Provide direct steering feedback and allow for camber adjustment (front requires aftermarket adjustable arms for significant changes).

🛡️ Enhanced Durability with 2-Year Warranty
The use of advanced internal components allows HKS to back this extreme-performance model with a 2-year / 40,000 km warranty, providing exceptional confidence in its long-term reliability.

Performance Philosophy

• Goal: To redefine the performance envelope of GT-R suspension by eliminating the traditional trade-off between race-track sharpness and street compliance. The focus is on limitless control, progressive feedback, and technological innovation.

• Focus: The definitive coilover for the track-focused GT-R enthusiast who refuses to sacrifice daily comfort. It is engineered for owners who frequent circuits or drive aggressively on backroads and seek the ultimate in handling precision, stability, and a supernatural lack of vibration.

Installation & Tuning Notes

• 🔧 Professional Installation, Alignment, & Corner Balancing REQUIRED
  Installation must be performed by a professional competition-oriented shop. A precision performance alignment and corner balance are mandatory to realize the system’s potential and ensure safety. Front camber beyond factory specs requires aftermarket adjustable arms.

• ⚠️ Critical Setup & Synergy

  • Aggressive Tire/Wheel Fitment: The tested setup uses aggressive 20x10J front and 20x11J rear wheels with 285-section tires. Similar high-grip, wide tire setups are recommended to match the suspension’s capabilities.

  • Use Provided Data: The Fuji Speedway damper and alignment settings are the engineered starting point for performance.
