OVERVIEW

Transform the handling dynamics and stance of your G16E-GTS powered hatchback with the HKS Hipermax S Full Coilover Kit for the Toyota GR Corolla. Designed to balance everyday driving comfort with sharp, responsive track handling, the Hipermax S series features 30-way damping adjustment and single-tube shock construction. Engineered with HKS's Dual PVR (Preload Valve System) technology, these coilovers eliminate unwanted suspension pitch and roll while maintaining excellent bump absorption over harsh road surfaces.
