HKS Hipermax IV 4 GT Coilovers, RWD - Infiniti Q50 Sedan V37

So HKS has developed the Hipermax IV GT for lower stance style and to support the vehicle's maximum potential. They have adjusted all four corners to have balanced damping force rate, allocated stroke, vehicle height balance, etc. by putting the car through its paces. These tests resulted in a stable and balanced pressure for each wheel. All these settings will provide the driver with the best performance while keeping safety as the priority. Also they have set the damping force and piston speed for the best comfort possible. They recommend the dial-30 for most comfortable ride.
