HKS 80300-AF005 HIPERMAX S Coilover Kit Subaru Legacy BP5/BL5

The HKS HIPERMAX S Full Coilover Kit represents the evolution of HKS suspension technology, combining advanced damping characteristics, enhanced durability, and refined aesthetics into a complete performance suspension system. This kit is specifically engineered for the Subaru Legacy BP5/BL5 chassis, delivering an optimal balance between comfortable daily driving and spirited performance handling.

Advanced Technology Features:

• Dual Preload Valve System (PVS) suppresses unnecessary damping force at higher piston speeds for improved ride comfort without sacrificing driving performance
• Wide Range (WR) Needle Jet design expands damping force adjustment range, allowing precise tuning for various driving conditions from city streets to spirited backroad driving
• 30-level damping force adjustment mechanism provides fine-tuned control over suspension behavior
• Monotube damper construction separates gas and oil for stable, consistent damping characteristics under heat and load
• Advanced Bump Stop Rubber reduces body roll while maintaining excellent ride comfort, outperforming conventional hydraulic bump stops
• Low friction technology utilizing advanced tribology enhances durability and reduces internal friction for improved ride quality and handling response

Premium Construction and Components:

• Length-adjustable shock bodies allow ride height adjustment without pre-loading springs
• Shot-blasted aluminum top mounts with machined chamfering for enhanced aesthetics and rigidity
• Reinforced rubber upper mounts absorb minor vibrations while providing firmer control than stock mounts
• Cold-formed high-grade springs manufactured in-house at HKS facilities with printed spring rates for easy identification
• PNE coating provides 5x better corrosion resistance compared to standard galvanizing
• DURA BOOTS protect damper shafts from contaminants for extended service life

HKS Flat Ride Concept:

Built around HKS's proprietary Flat Ride Concept (FRC), the HIPERMAX S smooths out low-speed harshness and initial input roughness from road imperfections while maintaining excellent body control during cornering and dynamic driving. This creates a refined, controlled ride quality that makes the system ideal for street use without compromising performance capability.

Quality Assurance:

The HIPERMAX S series features optimized internal components and improved quality control, backed by an industry-leading 3-year warranty—triple the coverage of previous MAX IV GT series models. Each kit undergoes extensive real-world validation testing before leaving HKS facilities in Japan.

What's Included:

Complete full coilover kit with pre-assembled dampers, spanner wrenches, and damper adjustment tool for simplified installation and setup.
