HKS Hipermax S Coilover Kit Subaru WRX / STI 2015-2021 | 80300-AF009P

Product Description

OVERVIEW:

 

Introducing the HKS Hipermax S Coilovers tailored for the 2015-2021 WRX/STI. Nine years after the debut of the MAXIV GT, the HIPERMAX S series emerges, setting a new benchmark for "Driving Comfort" by enhancing damping force, durability, and aesthetics.

Beyond conventional ride comfort and handling prowess, the focus shifts towards a holistic notion of "Driving Comfort," prioritizing both ride ease and the confidence instilled by superior handling and drivability. It's a meticulous equilibrium that meets the diverse demands of street driving.

Retaining the single-tube structure, the HIPERMAX S series separates the gas and oil chambers, facilitating the use of a larger piston diameter for consistent and stable damping force. Building upon the Pre-load Valve System from its predecessors, the new "Dual PVS" minimizes high-speed damping while curbing unnecessary motion, thanks to enhanced needle design and a widened oil relief channel. The 30-step adjustment system now offers more discernible gradations, catering to a spectrum of street driving preferences with softer adjustment options.
