The legendary HIPERMAX Coilover line has just been expanded with HKS' new HIPERMAX R Coilovers. Developed from the proven MAX IV SP Coilover series, the HIPERMAX R evolves the performance coilover to the next level. The HIPERMAX R features three key technological upgrades; Super Response Fluid, Low Vibration Spring, and an upper spring retainer exclusive to the HIPERMAX R. The Super Response Fluid is a newly developed oil that improves the characteristics of the damping force and suppresses temperature change for better handling performance. The exclusive high-strength Low Vibration Spring is manufactured with 210k-grade wire rods to reduce weight and improve steering response. Finally, the upper spring retainer allows the damping axis and spring load lines to align coaxially, resulting in smoother damping. Please refer to the attached excel file for all HKS HIPERMAX R part numbers.


  • Super Response Fluid high-quality damper oil improves handling performance
