30-Way Damping Adjustment:

The 30-way damping adjustment provides precise control over compression and rebound characteristics. This wide adjustment range allows you to fine-tune the suspension for different driving conditions - softer settings for street comfort, stiffer settings for track grip, or specialized setups for drifting. The adjustment knobs are easily accessible, allowing you to experiment with different settings to find the perfect balance for your driving style and application. The 30-way range provides more granular tuning than typical 16-way or 24-way systems.

Monotube Design:

HKS's monotube shock design offers superior heat dissipation compared to twin-tube shocks. The single-tube construction allows the shock oil to contact the outer tube directly, transferring heat more efficiently to the surrounding air. This improved cooling maintains consistent damping characteristics during extended track sessions or aggressive street driving, preventing fade and maintaining predictable handling. The monotube design is a hallmark of premium coilover systems.

Independent Height Adjustment:

The independent height adjustment system allows you to set your desired ride height without affecting spring preload. This is a critical feature that separates quality coilovers from budget options - it ensures the springs are properly loaded regardless of ride height, maintaining optimal suspension geometry and preventing spring separation. The threaded shock body provides a wide range of height adjustment to achieve your desired stance.

Pillow Ball Upper Mounts:

Pillow ball upper mounts replace the factory rubber mounts with precision spherical bearings. This upgrade reduces deflection under load, improving steering response and feedback. The pillow ball design also allows for camber adjustment (where applicable), enabling proper alignment for lowered vehicles and track-focused setups. The improved response and reduced compliance make the steering feel more direct and connected.

HIPERMAX S Series:

The HIPERMAX S represents HKS's premium street/sport coilover line, engineered for enthusiasts who demand adjustability and performance without sacrificing street drivability. The "S" designation indicates this is a street-focused system that balances performance with comfort. HIPERMAX S coilovers deliver the adjustability and performance needed for track days while maintaining the ride quality required for daily driving. This makes them ideal for dual-purpose builds.

S14/S15 Application:

The S14 240SX (1995-1998) and S15 Silvia (1999-2002) are legendary drift and track platforms known for their balanced rear-wheel-drive handling. Both chassis benefit significantly from suspension upgrades, as the factory suspension was designed for comfort rather than performance. HKS HIPERMAX S coilovers unlock the S14 and S15's handling potential for drift, track, and street performance. The adjustability allows you to dial in the perfect setup for your specific application.

Made in Japan:

HKS HIPERMAX S coilovers are manufactured in Japan to exacting quality standards. Japanese manufacturing is renowned for precision, quality control, and attention to detail. The "Made in Japan" designation ensures you're getting a product engineered and manufactured to the highest standards. HKS's Japanese heritage and manufacturing excellence are reflected in every component of the HIPERMAX S system.
