  • The ride comfort required for daily use and sports performance such as stability has been improved in a awell -balanced tune without losing stock comfortability.
  • Adopting the conventional shock absorbers, makes the car easier to read and allows the driver to have better control.
  • While maintaining the stability of touring and daily driving, it pursues damping characteristics with the
  • firm when moving intensely, and stability and controllability in the limit range are greatly improved.
  • Testing various spring rates resulted in a suspension with a spring rate of F = 69 Nm (7 kg)/R = 59 Nm
  • (6 kg) and a spring length of F = 200 mm (series barrel type)/R = 250 mm (series barrel type) that wa suitable for a wide range of users.
  • High spring rates are recommended for use in hill climbs and mini circuits or use with high grip tires.
  • When the spring rate is changed, the spring length is changed to F = 170 mm/R = 220 mm.
  • The recommended dial damping force for rate rate-up is F: D = 15/R: D = 13.
  • When considering a circuit attack, it is recommended to swing the rear suspension's toe angle to out.
  • Understeer becomes less to come out, and you can step on the gas pedal earlier when you stand up from the corner. Controls of understeer and oversteer are also improved.


  • 20 SPEC further improves ride quality, stability and comfort over MAXIV with latest technologies.
  • Reducing the damping force at the rebound side provides new suspension with more flexible moving and greatly improves grip feeling.
  • Appropriate bump damping force setting reduces excessive damper movement and promotes flat ride feel.
  • The suspension provides high stability and flat ride feeling with less stiffness even on the rough road.
  • Stability provides a smooth moving and weight transfer and it brings the mild steering feel.
  • Increases the stroke amount at the rear side, stability and traction performance. New soft type bump stops also improves stability and driving comfort.
