HKS HIPERMAX R Coilovers For Nissan Skyline R34 GTR 80310-AN003

The HKS Hipermax R Coilover Kit for the Nissan Skyline GT-R R34 represents the pinnacle of precision suspension engineering, designed for enthusiasts who demand total control, superior response, and unrivaled performance. Developed through extensive motorsport testing, this premium system delivers exceptional balance between track-ready handling and street comfort. Each unit features finely tuned damping characteristics that allow drivers to experience sharper steering response, reduced body roll, and greater stability during high-speed cornering, all while maintaining a compliant ride for everyday use.

Crafted for the legendary BNR34 platform, the Hipermax R series embodies HKS’s latest suspension innovations, combining cutting-edge single-tube damper technology with their proprietary Super Response Fluid and Low Vibration Springs. These advancements ensure consistent damping performance, reduced friction, and enhanced heat dissipation under intense driving conditions. The result is a suspension system that offers precision adjustability for both height and damping, allowing enthusiasts to customize their setup for street cruising or circuit dominance with confidence.

When installed, the HKS Hipermax R Coilover Kit transforms the Skyline GT-R R34 into a more responsive, agile, and predictable machine, delivering improved traction and balance that elevate the driving experience beyond OEM capabilities. Engineered and tested by one of Japan’s most respected performance brands, this kit delivers race-proven technology directly to the street, making it the ultimate suspension upgrade for serious Nissan GT-R owners who value authentic performance and durability.

• Stock suspension is generally tuned for comfort, broad usability, and has limited adjustability. The HKS kit is performance‐oriented but still retains enough comfort for street use.

• The adjustability (height + damping) gives you flexibility: you can tune for street, track days, or a mix. Many lesser kits may offer height or springs only, but not the full adjustability.

• The proprietary tech (SRF oil, high strength LVS springs, single tube design) offers improved durability and performance consistency under stress (high cornering forces, heat build‐up) compared to generic kits.

• Better steering response, more precise suspension behavior in dynamic situations: you’ll likely get a "tighter" feel, less body movement, and more confidence.

• Because it is vehicle‐specific (for the BNR34 in this case) the fitment, mounting, spring/damper harmonization, and tuning have been engineered for that exact chassis. That’s typically better than a universal “generic” coilover
  

• The spring rates (14 kgf/mm front, 12 kgf/mm rear for BNR34) are significantly stiffer than stock. If you use very aggressive settings (track oriented), ride comfort will diminish. For daily driving you may want to lean toward the softer end of the adjustment spectrum.

• Alignment: After installing coilovers you MUST get a proper alignment (camber, toe, caster) to maximise benefit and minimise uneven tire wear or handling quirks.

• Maintenance / warranty: HKS lists a 2-year warranty for the HIPERMAX R series. 
  

• Adjacent upgrades: If your car has stiff bushings, big tires/wheels, altered suspension geometry, you’ll want to make sure the rest of the car supports the upgraded coilovers (e.g., sways, arms, tires).
