Adjusting your vehicles suspension is one of the easiest ways to instantly improve overall performance. HKS offers a complete line of performance coilover suspension systems. The HKS Hipermax IV line is their top tier setup, tuned and designed for street performance and race applications. HKS utilizes its experience from 35 years of circuit, GT, drift, and drag racing to bring you the cutting edge in suspension technology.

The HKS Hipermax IV GT coilovers for the Scion FR-S and Subaru BRZ are a top tier performance coilover setup that are perfect for street and some track applications. These coilovers use hardened anodized aluminum mounts and parts where possible and powder-coated steel mounts for high stress parts. HKS uses high quality springs but a Swift Spring upgrade is also available. If you are looking for high quality but very streetable coilovers than look no further!
