HKS Hipermax S Coilovers - Subaru WRX STI

HKS unveils the future of the new Coilover series for the street with the HIPERMAX S series.  The three existing MAX IV GT series have become the HIPERMAX S.  Nine years have passed since the launch of the MAXIVGT, and during that time HKS has developed new technologies.  In addition to all three conventional model characteristics, the HIPERMAX S series has new features such as dual PVS, improved shape of needle jet and bump stop rubber, and low friction technology.  Also, it comes with a three-year warranty due to optimized internal parts and quality improvement.  The HIPERMAX S series offers the best ride in HKS suspension history.
