Developed through extensive HKS testing on the RZ High Performance variant specifically, the kit delivers a well-balanced tune that improves roll rigidity, cornering stability, and overall drivability without sacrificing the GR Yaris's factory ride quality. Factory spring rates of 69 N\/mm front and 59 N\/mm rear were selected after testing multiple configurations to suit a wide range of drivers - from daily street use to winding roads and occasional performance driving.\u003c\/p\u003e\u003cp\u003e The kit features an inverted monotube front damper with the Dual PVS and WR Needle system for refined, wide-range damping control across 30 adjustment steps. The rear uses a normal-type monotube damper in a separated spring\/damper layout - note that the front is a coilover-integrated unit while the rear spring and damper are separate components. HKS recommends increasing spring rates (with free length adjustments) for hill climbs, mini track use, or high-grip tire applications. The kit ships at a factory drop of approximately 25mm front and 26mm rear, with an adjustable range of up to 45mm front and 47mm rear below stock. Backed by HKS's 3-year \/ 60,000 km warranty and confirmed discontinued by HKS Japan - verify stock availability before ordering.\u003c\/p\u003e\u003cmeta name=\"description\" content=\"Upgrade your 2020-2024 Toyota GR Yaris with the HKS HIPERMAX S coilover kit, designed for optimal performance and comfort. \"\u003e\u003cmeta name=\"keywords\" content=\"HKS HIPERMAX S coilover kit, Toyota GR Yaris suspension upgrade, adjustable damping coilover, performance suspension for GR Yaris, Toyota GR Yaris full coilover kit, inverted monotube damper kit, high-performance coilovers Japan, GR Yaris aftermarket suspension, sports suspension for AWD vehicles, HKS automotive performance parts\"\u003e","brand":"HKS","offers":[{"title":"Default Title","offer_id":53856573292863,"sku":"HKS80330-AT025","price":2550.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/wcaperformance.com\/products\/hks-20-24-toyota-yaris-gxpa16-hipermax-s-full-kit-1","provider":"WCA Performance","version":"1.0","type":"link"}
