HKS 80330-AT030 HIPERMAX S Coilover Full Kit for 23-26 Toyota GR Corolla GZEA10

Vehicle Fitment

• 2023-2026 Toyota GR Corolla (Core, Circuit Edition, Morizo Edition - GZEA10 Chassis, G16E-GTS 1.6L Turbocharged I3, AWD)

Fitment Notes

• Covers all GR Corolla trims including Core, Circuit Edition, and Morizo Edition on the GZEA10 platform - all share the same suspension mounting points.
• For AT (automatic transmission) vehicles, HKS recommends raising the front ride height by 3mm from the factory setting due to the added weight differential versus MT models.
• This kit is GR Corolla-specific and is not shared with the standard Corolla or GR86 chassis - do not cross-reference with other HKS AT-series coilover kits.
• Height data (+3mm / -51mm front; +7mm / -70mm rear) is measured relative to factory stock ride height. Lowest values may not be road legal; verify local regulations before running minimum height.
• Can only be shipped via UPS or FedEx - not eligible for standard freight or LTL shipping.

Features

• FLAT RIDE CONCEPT - engineered to improve everyday ride comfort while preserving the GR Corolla's factory-tuned performance handling balance
• Large-diameter monotube damper separates gas and oil chambers for stable, fade-resistant damping under heat and repeated use
• 30-level damping force adjustment - adjustable from comfort-oriented street tuning to firm, performance-focused settings
• Dual PVS (Dual Preload Valve System) provides independent control of low- and high-speed damping for precise, platform-specific ride tuning
• Full shock-body length adjustment lowers the car without pre-loading the spring, preserving suspension geometry and spring rate integrity at any ride height
• DURA BOOTS shaft protection shields the damper shaft from road debris and contamination for extended service life
• 3-year / 60,000 km warranty - validated through 60,000 km of real-world testing prior to production release

Product Description

The HKS 80330-AT030 HIPERMAX S is a full coilover kit purpose-engineered for the 2023+ Toyota GR Corolla (GZEA10), covering all trims including the Core, Circuit Edition, and Morizo Edition. Built around HKS's FLAT RIDE CONCEPT, the kit targets the GR Corolla's unique balance challenge - a turbocharged AWD hot hatch with factory suspension tuned to a high standard - and improves everyday ride refinement without sacrificing the precise, planted handling the GR Corolla is known for. The rear spring rate is intentionally set higher than the front (88 N/mm vs. 69 N/mm) to maximize rear stability under the GR Corolla's GR-FOUR AWD dynamics and high-speed cornering loads.

The large-diameter monotube damper with Dual PVS technology provides 30 levels of damping adjustment and independent control of low- and high-speed damping, allowing the kit to serve equally well as a comfort-biased daily setup or a firm track configuration. Full shock-body length adjustment allows ride height reduction without spring pre-load, and DURA BOOTS protect the shaft for long-term durability. The kit is backed by HKS's 3-year / 60,000 km warranty and validated over 60,000 km of testing - making it one of the most comprehensively developed coilover options available for the GR Corolla platform.
