Features

• Inverted front damper layout reduces unsprung weight and increases lateral rigidity for improved steering feel and cornering stability
• Single-tube (monotube) damper construction separates gas and oil for consistent, heat-stable damping across sustained hard use

• Dual Preload Valve System (Dual PVS) reduces unnecessary high-speed damping force for improved ride comfort without compromising sport response
• Rear helper spring (19.8 N/mm) prevents spring float at full droop and improves low-speed packing behavior
• Strengthened rubber upper mounts absorb small chassis vibrations while tightening mount response over stock
• Length-adjustable shock body allows lowering without spring preload, preserving full suspension travel
• DURA BOOTS and PNE corrosion-coated threads for long-term durability

Product Description

The HKS 80330-AM001 Hipermax S is a complete front and rear coilover kit for the 2007-2015 Mitsubishi Lancer Evolution X (CZ4A) featuring reinforced rubber front upper mounts for a balance of performance and street compliance. Using the same inverted front damper design, monotube construction, Flat Ride Concept (FRC) tuning, and Dual Preload Valve System (Dual PVS) as the pillow ball variant, this kit delivers genuine performance handling from the CZ4A's AWD platform while allowing the strengthened rubber upper mounts to filter small chassis vibrations for improved daily comfort. Front spring rates of 98 N/mm and rear rates of 69 N/mm are calibrated for the Evo X's performance character, with a 19.8 N/mm rear helper spring maintaining damper contact through the full suspension travel range.

Ride height at shipment is -36 mm front and -19 mm rear, with front adjustability down to -60 mm and rear down to -57 mm from stock ride height. The 30-step WR Needle damping adjustment is accessible at both ends without disassembly, with rear fine-tuning available via the included wire adjuster. Drivers prioritizing camber tuning capability or the most direct steering feedback should consider the pillow ball upper mount variant, 80330-AM001P. This kit supersedes part number 80300-AM001, ships via UPS or FedEx only, and is backed by HKS's 3-year / 60,000 km manufacturer warranty.
