Fitment Notes

• Covers both the X90 generation (GX90, JZX90, JZX91, SX90 - 1992-1996) and the X100 generation (GX100, JZX100, JZX101 - 1996-2000) on a shared coilover application - same mounting points across all chassis codes listed.
• Rear damping force is wire-adjustable (Rear: Yes / Front: N/A) - the rear damping dial is remotely accessible without removing the damper. Front damping is adjusted at the damper body.
• Helper springs are included front and rear (Spring Rate: 19.8 N/mm each) to maintain spring contact during full extension.
• Spring rate change is supported: recommended range ±20 N/mm (±2 kgf/mm) front and rear. Free length changes with rate change - consult HKS for correct spring length when substituting rates.
• Can only be shipped via FedEx or UPS - not eligible for standard freight or LTL shipping.

Features

• FLAT RIDE CONCEPT - engineered for a well-balanced street and occasional track tune suited to the X90/X100 FR platform's weight distribution and chassis characteristics
• Large-diameter monotube (normal type, front and rear) damper separates gas and oil chambers for stable, consistent damping performance under heat and repeated use
• 30-level damping force adjustment front and rear - rear adjustable via remote wire without removing the damper unit
• Dual PVS (Dual Preload Valve System) suppresses unnecessary damping force at high piston speeds for improved ride comfort without sacrificing performance
• WR Needle (Wide Range damping adjustment) expands the oil relief channel for a broader, more precise 30-step adjustment range
• Helper springs front and rear maintain spring contact at full extension for consistent ride behavior across the full height adjustment range
• 3-year / 60,000 km warranty - validated through 60,000 km of real-world testing prior to production release

Product Description

The HKS 80330-AT009 HIPERMAX S is a full coilover kit engineered for the 1992-2000 Toyota Mark II, Chaser, and Cresta across both the X90 (GX90, JZX90, JZX91, SX90) and X100 (GX100, JZX100, JZX101) platform generations. All chassis codes listed share the same mounting points and are covered by this single application. The kit is tuned with a notably high front spring rate of 137 N/mm (14.0 kgf/mm) to suit the FR platform's front-heavy weight distribution and the natural understeer tendencies of the inline-6 powered X90/X100 body - paired with a more compliant 88 N/mm rear to allow rear rotation under driver input.

A standout feature of this application is the wire-adjustable rear damping - the rear dial is remotely accessible without removing the damper, making on-the-fly tuning practical for road or track use. Helper springs front and rear maintain spring contact at full extension to prevent floating and maintain consistent ride behavior across the full 58mm drivable front adjustment range. The Dual PVS and WR Needle system provide 30 steps of damping adjustment, and the kit ships with all hardware including rear adjustment cables. Backed by HKS's 3-year / 60,000 km warranty, this kit is one of the most complete and well-developed HIPERMAX S options available for the classic JZX platform.
