HKS 80330-AT010 Hipermax S Coilover Suspension Full Kit

The HKS Hipermax S Series (80330-AT010) is a full coilover suspension kit engineered for the Toyota Supra JZA80 (2JZ-GTE). Representing a complete evolution of HKS's legendary MAX IV GT lineup, the Hipermax S integrates advanced damping technology, low-friction internals, and refined ride comfort into a single street-focused coilover system — delivering the best ride quality in HKS suspension history.

Key Features:

• Dual PVS (Dual Preload Valve System): Suppresses unnecessary damping force at higher piston speeds for a significant improvement in ride comfort without sacrificing handling performance
• Wide-Range Damping Force Adjustment: An improved Needle Jet design expands the damping adjustment range, allowing fine-tuning across a broader variety of driving stages and conditions
• Evolved Bump Stop Rubber: A redesigned bump stop profile reduces body roll while maintaining ride comfort — performance that cannot be achieved with standard hydro bump stop rubber
• Low Friction Technology: Advanced tribology engineering delivers higher durability and lower internal friction compared to previous HKS coilover generations, contributing to improved ride quality and handling response
• Height-Adjustable Shock Bodies: Length-adjustable damper bodies allow ride height lowering without preloading the spring
• 3-Year Warranty: Backed by an industry-leading 3-year warranty, a significant upgrade from the 1-year coverage offered with the previous MAX IV GT series

Specifications:

• Spring Rate: Front 137 N/mm (14.0 kgf/mm) | Rear 78 N/mm (8.0 kgf/mm)
• Free Spring Length: Front 200 mm (Straight) | Rear 250 mm (Straight)
• Ride Height Adjustment at Shipment (Upper–Lower): Front −31 mm (0 to −92 mm) | Rear −13 mm (0 to −77 mm)
• Note: Not compatible with vehicles equipped with REAS. Installable if the hydraulic system is removed.

The Hipermax S Full Kit ships pre-assembled and includes all hardware needed for installation, making it an ideal upgrade for enthusiasts seeking a meaningful balance of street comfort and track-ready handling performance.
