HKS Hipermax S Full Coilover Kit – Toyota Chaser / Mark II / Cresta JZX100 1996–2001 | Street & Track Damper System

The HKS Hipermax S Full Coilover Kit for the Toyota JZX100 chassis (1996–2001) is a complete 4-corner coilover suspension system engineered by HKS for the Chaser, Mark II, and Cresta platforms sharing the JZX100 chassis — one of the most iconic Japanese rear-wheel drive platforms of the late 1990s. Powered by the 1JZ-GTE turbocharged inline-six and built on a rear-wheel drive platform with a long wheelbase and well-sorted suspension geometry, the JZX100 is a highly capable street and track platform that rewards quality suspension tuning. The Hipermax S delivers the ride height adjustability, damper tuning capability, and spring rate selection that the JZX100's performance potential demands — in a complete kit that replaces the factory suspension at all four corners. Whether the build direction is street performance, track day, or drift, the HKS Hipermax S gives the JZX100 owner the tools to set the car's suspension to match their specific application.

Key Features:

• Complete 4-corner coilover kit — full front and rear coilover assemblies replacing the factory suspension at all four corners — everything required for a complete suspension upgrade in a single purchase
• HKS Hipermax S damper technology — HKS's street and track-oriented damper specification — engineered for the JZX100's suspension geometry, spring rates, and performance requirements
• Ride height adjustability — adjustable ride height via threaded spring perch — set the JZX100's ride height to match your specific application and aesthetic requirements
• Damper adjustment — adjustable damper settings for tuning the suspension's response characteristics to match your driving style and application — softer for street comfort, firmer for track and drift precision
• JZX100 specific — engineered for the Toyota Chaser, Mark II, and Cresta JZX100 chassis (1996–2001) — correct geometry and spring rates for the JZX100's suspension layout
• HKS engineering quality — manufactured by HKS, one of Japan's most respected performance brands with extensive development experience on the JZX100 platform
• Complete kit — includes all four coilover assemblies and required hardware for installation

Performance Benefits:

• JZX100 Platform Potential: The Toyota JZX100 — Chaser, Mark II, and Cresta — is one of the most respected Japanese rear-wheel drive platforms of the late 1990s. The 1JZ-GTE's turbocharged inline-six delivers strong, linear power that is well-matched to the JZX100's rear-wheel drive chassis, and the platform's long wheelbase and well-sorted suspension geometry provide a stable, predictable handling foundation that responds well to quality suspension tuning. The HKS Hipermax S is engineered to unlock that potential — providing the ride height, spring rate, and damper tuning capability to optimize the JZX100's suspension for the driver's specific application.
• Ride Height Adjustment: The Hipermax S's threaded spring perch allows precise ride height adjustment at each corner — enabling the JZX100 to be set at the correct ride height for track use (lower centre of gravity, improved aerodynamic balance) or street use (adequate clearance for road conditions). The ability to set ride height independently at each corner also allows corner weight adjustment for track and drift applications where balanced corner weights contribute to more predictable and controllable vehicle behaviour.
• Damper Tuning: The Hipermax S's adjustable damper settings allow the suspension's response characteristics to be tuned to match the driver's preferences and the application's requirements — from a softer, more compliant setting for street driving comfort to a firmer, more responsive setting for track use where body motion control and transient response are priorities. For drift applications, damper tuning is particularly important for controlling the car's rotation initiation and angle maintenance characteristics.
• Improved Handling Precision: The Hipermax S's coilover design — with matched spring rates and damper valving engineered for the JZX100's suspension geometry — delivers significantly improved handling precision over the factory suspension. Reduced body roll, improved transient response, and more consistent suspension geometry under load contribute to a more precise, more confidence-inspiring handling character across all driving applications.

Specifications:

Fitment Information:

• Toyota Chaser JZX100 — 1996–2001
• Toyota Mark II JZX100 — 1996–2001
• Toyota Cresta JZX100 — 1996–2001
• Note: The JZX100 chassis was shared across the Chaser, Mark II, and Cresta nameplates — verify that HKS80300-AT009 is the correct part number for your specific JZX100 variant and market specification before ordering. A four-wheel alignment is required after coilover installation. Professional installation by an experienced JZX100 suspension specialist strongly recommended.

What's Included:

• HKS Hipermax S front coilover assemblies (pair)
• HKS Hipermax S rear coilover assemblies (pair)
• All required mounting hardware
• Refer to HKS product documentation for complete kit contents and spring rate specifications

Installation Notes:

• Professional installation by an experienced JZX100 suspension specialist strongly recommended — coilover installation requires correct torque specifications, correct spring perch height setting, and a four-wheel alignment after installation
• A four-wheel alignment is required after coilover installation — do not drive the vehicle at speed before a full alignment is performed
• Set ride height with the vehicle at kerb weight (fuel, fluids, and driver weight) for accurate ride height measurement — setting ride height on an unloaded vehicle will result in incorrect ride height under normal driving conditions
• Set damper adjustment to the manufacturer's recommended baseline setting before the first drive — adjust from the baseline after evaluating the suspension's behaviour on your specific roads and track
• Inspect all suspension components (control arms, bushings, ball joints, tie rod ends) before installation — the JZX100's suspension bushings deteriorate with age and should be inspected and replaced if worn before installing new coilovers. These cars are now 25–30 years old and worn bushings are common.
• For drift applications: set damper adjustment and spring perch height with the specific requirements of drift technique in mind — consult an experienced JZX100 drift setup specialist for application-specific recommendations

Why HKS?

HKS is one of Japan's most respected and longest-established performance brands — with a product lineup spanning coilovers, exhaust systems, air intakes, turbochargers, ECU tuning systems, and engine components for a wide range of Japanese performance platforms. HKS has a long history of development on the JZX100 platform — one of the most iconic Japanese rear-wheel drive platforms of the late 1990s and a staple of the Japanese drift and performance scene. The Hipermax S JZX100 kit reflects that platform-specific development experience. For JZX100 owners who want a coilover system from a brand that genuinely understands the platform's suspension geometry and performance potential, HKS Hipermax S is a well-regarded choice.

Perfect For:

• Toyota Chaser, Mark II, and Cresta JZX100 owners seeking a significant suspension upgrade over the factory setup — improved ride height adjustability, damper tuning, and handling precision for street and track use
• JZX100 drift builds where ride height, spring rate, and damper tuning are critical for correct rotation initiation, angle maintenance, and overall drift setup
• JZX100 track day and time attack builds where the factory suspension's ride height, spring rates, and damper characteristics are limiting factors in handling performance
• Street performance JZX100 builds where a quality coilover system delivers improved handling precision and a lower, more aggressive stance without sacrificing daily drivability

Note: Verify JZX100 variant and market specification compatibility before ordering. Four-wheel alignment required after installation. Professional installation strongly recommended. Inspect JZX100 suspension bushings before installation — replace if worn. Set ride height at kerb weight for accurate measurement.
