HKS Hipermax R Coilovers (ZN8)

We have achieved an unprecedented balance of exhilarating driving control and adaptability from the circuit to winding roads, refining the ride experience to create the "ultimate multi-performer."

The exclusive Hipermax R features our newly developed damper fluid "SRF" and high-strength springs "LVS," enabling a harmonious blend of superior handling and comfort. Respecting the GR86's inherent character, even with high-grip tires, it maintains the authentic FR-like maneuverability, offering a delightful sense of control.

By actively utilizing the bump rubber, a result of HKS's extensive research, we enhance the stability during cornering, ensuring a consistent tire contact patch and preventing sudden loss of grip.

The setup for the circuit was performed at the Fuji Speedway Racing Course (with ADVAN A052 tires). For optimal performance on this track, we recommend adjusting the damping force dial to approximately 5-10 stages for both front and rear.
