Product Details
These HKS Hipermax S GR Yaris coilovers fit the 2020-2024 Toyota GR Yaris (GXPA16).
HKS builds these GR Yaris coilovers with 7 kgf/mm front and 6 kgf/mm rear springs and 30-level damping adjustment. The GR Yaris is a Japan-market (JDM) car.
This is the redesigned Hipermax S, built around HKS's Flat Ride Concept: the chassis stays level through mid-corner load transfer and stays composed over broken pavement. Every 80330-series kit is built in Japan and stays fully rebuildable through HKS.
