Introducing the HKS HIPERMAX S Coilover Kit, engineered for the Subaru Impreza WRX and STi models, which redefines “Driving Comfort” by seamlessly blending ride comfort with exceptional handling performance and drivability. This cutting-edge system offers an unparalleled balance that meets all the demands of street driving, ensuring peace of mind through its robust handling capabilities.

With 30 levels of adjustable damping, drivers can fine-tune their vehicle’s suspension for a tailored driving experience that prioritizes both comfort and performance.

Dual PVS

• The existing preload valve system was improved by HKS to create the dual-preload valve system in order to prevent excessive dampening forces from being generated at higher piston speeds. This offers a drastic enhancement in ride comfort without compromising the driving performance

Wide Range Damping Force Adjustment Mechanism

• The modified form of the needle jet expands the scope of damping force regulation, this enables HKS to take on driving across a broader selection of stages.

Evolution of Bump Stop Rubber

• The new form of bump stop rubber decreases body sway and concurrently provides a smooth ride experience that cannot be accomplished through standard hydro bump stop rubber.

Low Friction Technology

• Using cutting-edge tribology technology, HKS has achieved greater durability and lower friction than its conventional products, this technology enhances ride comfort and driving performance.

3-Year Warranty

• The HIPERMAX S Series boasts a more extended warranty of three years compared to the one-year period provided by conventional MAX IV GT series, which is attributed to its optimized internal components and upgraded quality.
