HKS 80330-AT023CP HIPERMAX S Coilover Kit for 2020-2026 Toyota GR Supra B58 RWD

Vehicle Fitment

• 2020-2026 Toyota GR Supra 3.0 (Base, Premium, A91 Edition, A91 CF Edition - DB02 Chassis, B58 3.0L Turbocharged I6, 8-Speed Automatic, RWD)
• 2021-2026 Toyota GR Supra 3.0 Premium (DB22 Chassis, B58 3.0L Turbocharged I6, 8-Speed Automatic, RWD)
• 2022-2026 Toyota GR Supra 3.0 Manual (DB42 Chassis, B58 3.0L Turbocharged I6, 6-Speed Manual, RWD)

Fitment Notes

• This is the CP (Canceller Package) variant - includes OEM electronic damper canceller components designed to eliminate suspension fault codes and warning lights when replacing the factory adaptive damper system. Required for a complete, warning-free installation on GR Supra models equipped with Toyota's Adaptive Variable Suspension (AVS).
• B58 engine (3.0L Turbocharged I6) fitment only. Does NOT fit the GR Supra 2.0 (DB15/DB11 - B48 2.0L I4); that application requires a different HKS coilover kit.
• For AT models, HKS recommends raising front ride height by 3mm from the factory setting due to weight differential versus the MT model (DB42).
• Drop heights listed are based on factory kit setting. Front adjustable range: -28mm to -57mm vs. stock. Rear adjustable range: -22mm to -75mm vs. stock.
• Can only be shipped via FedEx or UPS - not eligible for standard freight or LTL shipping.

Features

• HIPERMAX S FLAT RIDE CONCEPT - engineered to improve everyday ride comfort while preserving the GR Supra's B58-powered RWD performance characteristics and handling balance
• Large-diameter monotube damper construction separates gas and oil chambers for stable, consistent damping under heat and sustained high-speed driving
• 30-level damping force adjustment front and rear - spans from comfort-oriented street tuning to firm, track-ready settings
• Dual PVS (Dual Preload Valve System) provides independent control of low- and high-speed damping for precise platform-specific ride tuning
• Bundled OEM Canceller Package (CP) eliminates AVS fault codes and dashboard warning lights - no separate canceller purchase required
• Full shock-body length adjustment lowers the car without spring pre-loading, preserving suspension geometry at any ride height
• 3-year / 60,000 km warranty - validated through 60,000 km of real-world testing prior to production release

Product Description

The HKS 80330-AT023CP HIPERMAX S is a full coilover kit with bundled OEM Canceller Package, purpose-built for the 2020-2026 Toyota GR Supra 3.0 (B58, DB02/DB22/DB42 chassis), covering both the 8-speed automatic and 6-speed manual variants. The "CP" designation indicates this kit includes the hardware required to cancel the factory Adaptive Variable Suspension (AVS) system's fault codes and warning lights - eliminating the need to source a separate canceller kit. The notably high rear spring rate of 118 N/mm (12.0 kgf/mm) is intentional for the GR Supra platform, engineered to match the car's rear-biased weight distribution and high-speed stability demands while keeping the front rate at 69 N/mm for responsive, communicative steering feel.

The large-diameter monotube damper with 30-level adjustment and Dual PVS technology delivers a wide, usable damping range from refined daily driving to aggressive track tuning. Factory drop of 50mm front and 45mm rear from stock gives the GR Supra an immediately more aggressive stance, with a wide adjustable range allowing fine-tuning up or down from that baseline. Backed by HKS's 3-year / 60,000 km warranty and validated through 60,000 km of real-world testing, this is the most complete plug-and-play HIPERMAX S solution available for B58-powered GR Supra owners looking to eliminate factory adaptive suspension without additional components or warning lights.
