Generally, the damping force of the damper is compared by the numerical value when the piston speed is 0.3 m / s (expansion and contraction of 1 cm per second), but it is an area that does not occur much in daily driving such as when riding on a large step. Is.It is in the area where the piston speed is lower than 30 m / sec that suppresses the unpleasant roll that comes in the situation such as the entrance of a corner or the turning of the S shape.Our "Sports Damper" adopts a "High Precision Micro Low Speed ​​Valve" that generates a precise damping force from the moment the damper starts to move on the internal piston. By raising the damping force with a sharp curve from a very low speed range of 0.1 m / sec or less, we are aiming for the characteristic of responding quickly to steering operation.On the other hand, the damping force after 0.05m / sec, which causes pushing up, is gently suppressed, and the damping force on the contraction side is suppressed to a low level to give consideration to ride quality.The basis for setting the damping force is the unique damping ratio (balance between the spring constant and damping force) that matches the spring constant of the mass-produced spring.The optimum setting is made by combining both.

"Roll speed graph" is a sports damper (Red line) And mass-produced dampers (Blue line) We are comparing the process of roll speed from the moment the roll starts to the time it stabilizes.It can be seen that the maximum roll speed of the sports damper is reduced by about 25% (depending on the vehicle model) compared to the mass-produced damper, and the speed is gradually reduced thereafter.This characteristic suppresses the sensitive movement at the moment of turning the steering wheel, and leads to a firm and responsive feel.

The "roll amount graph" compares the passage of time from the start of the roll to the maximum roll amount. (The spring that determines the maximum roll amount is the same specification for both) Sports damper (Red line) Is a standard damper (Blue line), It takes longer to reach the maximum roll amount, and you can see that it is progressing slowly.In other words, it rolls gently after starting to turn the steering, which leads to a sense that the posture change of the car is stable.

The appearance of the damper is the same shape as the mass-produced product, and there is no change in the vehicle height or roll amount by combining with the recommended mass-produced spring.However, by installing it, the transitional characteristics of the roll change, and you can get the handling that is close to the driver's sensibility. (Simultaneous installation with AutoExe lowdown spring is also possible).
