• Durable construction ensures long-lasting performance under demanding driving conditions.

Construction & Design:

The Hipermax R coilovers feature a robust build quality with precision-engineered components designed to withstand the rigors of performance driving. The use of Super Response Fluid (SRF) in the dampers significantly improves oil viscosity stability, resulting in consistent damping response across a wide range of temperatures and driving conditions. The high-strength springs are carefully calibrated to reduce unwanted vibrations without compromising ride comfort, allowing for a lower ride height without harshness.

Each coilover is crafted to fit the GR Supra’s suspension geometry perfectly, ensuring optimal alignment and handling characteristics. The combination of advanced materials and meticulous engineering results in a suspension system that enhances both vehicle dynamics and driver confidence.
