Product Details
HKS Hipermax G coilovers for the 2015-2021 Subaru WRX STI 4DR (VAF) are tuned specifically for vehicles where ride quality, body control, and factory-level integration matter more than adjustability. The Hipermax G retains the stock upper mounts and full factory suspension stroke — giving the Subaru WRX STI 4DR a meaningful drop in stance without the harshness, geometry changes, or cabin noise that come with aggressive coilover setups.
A single-tube monotube damper, exclusive Low-Down Style springs, and HKS's PNE coating (5x the corrosion resistance of standard galvanizing) make the Hipermax G the right call for family vehicles, long commutes, and harsh road conditions. Each unit is assembled in an ISO 9001 facility in Japan and dyno-tested individually before shipping, so the Subaru WRX STI 4DR rides as cleanly on delivery as it does a hundred thousand miles later.
