HKS HIPERMAX R Coilovers For Nissan Skyline R32 GTR 80310-AN004

Enthusiasts building a high-performance Nissan Skyline R32 GT-R demand suspension that delivers sharp response and confidence on both winding roads and the circuit without sacrificing too much everyday usability. The HKS Hipermax R coilover kit (80310-AN004) stands out as a sport-oriented all-rounder engineered precisely for spirited driving, canyon carving, and track days. With noticeably stiffer spring rates—front 14 kgf/mm (137 N/mm) and rear 12 kgf/mm (118 N/mm)—paired with spherical pillow-ball upper mounts, this setup provides crisp steering feedback and precise handling that rubber-mounted kits simply cannot match.
The single-tube dampers feature 30-step damping adjustment on both front and rear, allowing fine-tuning across a wide usable range. HKS-exclusive technologies elevate the experience: Super Response Fluid (SRF) high-viscosity oil resists heat fade for consistent damping, while Low Vibration Spring (LVS) technology with an advanced retainer design delivers sharper response and smoother ride quality. Additional refinements include Dual Preload Valve (Dual PVS), a WR needle for broader adjustment range, optimized bump rubber, PNE anti-rust coating for easier height adjustment, and helper springs (19.8 N/mm) that maintain tire contact during hard cornering.
Factory drop is moderate (approximately -42 mm front / -17 mm rear) with excellent adjustable range, making it ideal for lowered yet practical setups. Compared to the more comfort-focused Hipermax S, the R leans track-biased with pillow-ball mounts and higher rates while remaining refined enough for street use. Developed and tested on circuits like Fuji Speedway, it excels at load following, reduced friction, and pure driving enjoyment.
