HKS 80140-BF003 Hipermax III Coilovers Subaru Impreza WRX STi 2005-2007
With the Hipermax III suspension series, the driver gains increased wheel control with improved performance of all vehicle dynamics and increased driver command in all conditions. Hipermax III combines track-quality control with excellent ride and handling characteristics at real-world street speeds. HKS' all-new Hiper Linear Piston Fluid Channel System damping system creates a positive relationship between piston speed and damping force, making it possible to produce a suspension that provides track-level control and feedback with exceptional ride quality at the same time. In addition, the Hipermax III is shock-body adjustable (most applications) to allow vehicle height adjustment without affecting spring rate and piston stroke. With the Hipermax III's range of adjustability, precise corner balancing can be achieved. Chrome-plated cylinder shafts provide excellent durability and newly-design rubber upper mounts reduce harshness.
