HKS HIPERMAX R Coilovers for GZEA14 Toyota GR Corolla

HKS HIPERMAX R Coilovers for GZEA14 Toyota GR Corolla

The HKS HIPERMAX R coilover system represents a pinnacle of suspension technology, specifically engineered for precision and performance. Featuring an innovative design that allows the damping axis and spring load lines to align coaxially, it dramatically reduces friction, ensuring smoother damping and a more responsive ride. This system incorporates exclusive high-strength springs made from 210k grade wire rods, optimized to reduce weight and improve steering response. Combined with a newly developed oil that enhances damper oil quality and viscosity, the HIPERMAX R system maintains superior handling performance by effectively suppressing temperature fluctuations caused by heat.

SRF – Super Response Fluid

• This exclusive newly developed oil features enhanced damper oil quality and viscosity, significantly improving the characteristics of the damping force and achieving superior handling performance. It effectively suppresses temperature variations caused by heat, ensuring a consistent and reliable driving experience.

LVS – Low Vibration Spring

• This exclusive high-strength spring is manufactured using 210k grade high-strength wire rods, designed to shorten wire length and reduce overall weight. The adoption of this advanced material enhances the steering response, providing a sharper and more agile driving experience.

Upper Spring Retainer

• Designed exclusively for HIPERMAX R, this feature allows the damping axis and spring load lines to align coaxially, reducing friction for smoother damping. This alignment enhances the overall efficiency and effectiveness of the suspension system, providing a more refined ride.
