Description

The HKS HIPERMAX S redefines the driving experience for the Nissan GT-R R35, masterfully balancing refined daily comfort with genuine sports performance. Engineered for the driver who uses their GT-R on both road and spirited drives, it transforms the supercar into a more sophisticated, composed, and versatile grand tourer. By utilizing advanced technologies and a carefully calibrated damping profile, it delivers a smooth, supple ride that absorbs imperfections while significantly improving chassis control and stability, creating a new benchmark for “driving comfort.”

Product Overview & Purpose

Designed for the enthusiast who values real-world usability, the HIPERMAX S prioritizes a qualitative transformation in ride quality, noise isolation, and high-speed composure over extreme track performance. It replaces the sometimes busy or harsh feel of the factory suspension (especially on older models) with a damped, “sticky” composure that flatters both the driver and the road. This system is the intelligent choice for enhanced daily enjoyment and confident backroad capability.

Product Highlights

🛋️ Redefining “Driving Comfort” – Smooth & Stable
The core philosophy is a transformative improvement in ride quality. The damping profile, aided by advanced Piston Valve System (PVS) and bumper rubbers, is meticulously calibrated to be smooth and supple. It effectively filters out high-frequency vibrations and sharp impacts, creating a quieter, more refined cabin environment and reducing driver fatigue on long journeys.

🏞️ Enhanced Stability & Confident Control
Beyond comfort, the HIPERMAX S delivers a substantial performance gain. It provides a meaningful increase in chassis control and high-speed stability, particularly noted for improving the “lack of stability over time” felt in some stock GT-Rs. The rear damping is tuned to suppress excessive movement, resulting in a more planted, secure, and predictable feel at highway speeds and during spirited driving.

🎛️ Wide-Range, Accessible Adjustability

• 30-Step Damping Adjustment (F/R): Easily tune the character from a plush, comfort-focused setting to a firmer, more responsive feel. HKS recommends tightening 2-3 clicks for crisper response on high-speed winding roads.

• Full-Length Ride Height Adjustment: Achieve a stylish, moderate lowering (approx. -12mm F / -13mm R at shipment settings) while maintaining optimal damper stroke.

• Convenient Rear Adjustment: Rear damping is adjusted via a convenient cable access in the trunk, no removal required.

🔧 Disables OEM Electronic Damping (Replaces with Superior Mechanical Tuning)
Installation replaces and disables the factory electronic damping system, as the HKS system provides a superior, fixed mechanical tune. Damping is now manually controlled via the adjusters, offering a more direct and consistent performance feel.
