HKS HIPERMAX S WRX STI Full Kit

The HKS Hipermax S series is an evolution from the MAXIV GT, engineered for superior "Driving Comfort" with advanced features in damping force, durability, and appearance. It utilizes a single-tube structure, allowing for separate gas and oil chambers and a large-diameter piston to achieve stable damping. The "Dual PVS" refines the previous MAX IV GT 20 Spec system, reducing high-speed damping while minimizing unnecessary movement. The improved needle shape expands the oil relief channel, making each of the 30 steps of adjustment more distinct, with softer options for street driving. "ADVANCED BUMP RUBBER" further enhances softness and offers variations for diverse vehicles, ensuring a natural and smooth experience. HKS also incorporated "PNE coating" for 5x better corrosion durability.
