HKS Hipermax R Coilovers for 1999-2002 Nissan Silvia (S15)

The HIPERMAX R Series Coilovers for the 1999-2002 Nissan Silvia (S15) have evolved all of handling, traction, and ease of fit to a new series by concentrating the technological capabilities cultivated over the past 9 years since the launch of MAX IV SP. The HIPERMAX R Series has achieved overwhelming performance that is unrivaled by any other brand.

For those who want to focus on sports driving performance on the race track, but do not want to sacrifice driving comfort in everyday use, choose the HIPERMAX R Coilovers.

New Technologies

• Super Response Fluid(Exclusive newly developed Oil)
  Improved damper oil quality and viscosity. Improves characteristics of Damping force, achieving great handling performance. Suppresses temperature change caused by heat
• Low Vibration Spring(Exclusive high-strength Spring)
  Manufactured with 210k grade high strength wire rods. Adopted to shorten wire length and reduce weight and Improves Steering response.
• Upper Spring Retainer(Exclusive for HIPERMAX R)
  Allow the damping axis and spring load lines to align coaxially. Reducing of friction and Smoother damping.

Additional Product Features

Dual PVS
We evolved the existing preload valve system to the dual preload valve system to suppress the generation of unnecessary damping force during higher piston speeds.This provides major improvement in ride comfort without influencing the driving performance.

Wide range damping force adjustment mechanism
The improved shape of the Needle jet expand the range of damping force adjustment. This makes us possible to handle driving on a wider range of stages.

Evolution of Bump stop rubber
A new shape of bump stop rubber reduces the body roll and achieves ride comfort at the same time which cannot be achieved with general hydro bump stop rubber.

Low friction technology
With advanced tribology technology, we have achieved even higher durability and lower friction than conventional products. This technology contributes to improved ride quality and handling performance.

Inverted Damper for Strut Type
Firm rigidity against stress has been achieved. It works to the advantage of various performances when driving, and provides excellent handling and ride comfort.
