Strong compression stage

For an even more precise steering

  • more direct steering
  • improved handling
  • pitch and roll movements of the body are reduced
  • Adaption to the tire stiffness

Reduced rebound stage

For a more comfortable setup

  • increased driving comfort
  • Adaption to the tire stiffness
  • Increased tire grip level at optimum wheel load changes

Lowspeed compression stage

at slow damper speeds

  • affects the body movements e.g. curvy passages
  • influences the pitch roll movements when accelerating
  • affects grip level and tire temperature
image

Highspeed compression stage

at fast damper speeds

  • affects the driving behavior when driving over:
    • transverse joints
    • short bumps
    • pot holes

Adjustable lowspeed compression damping influences the pitch and roll movements of your car when accelerating. You can also affect the body movement when driving over long-lasting lower frequency undulations in the road by adjustable low-speed compression valve. In contrast, the adjustable high- speed compression damping allows you to adapt to the damping characteristics over pot holes, short bumps, or transverse joints in the road.

Generally speaking: The tighter the compression damping is adjusted on the front axle, the more precise and direct the handling gets. On the rear axle, a sportier adjusted compression setup leads to increased track stability during load changes and helps to reduce oversteer.

Strong rebound stage

If you turn the adjustment knob clockwise, you increase the force of the rebound stage and you will get tighter handling. High rebound forces improve the handling, especially on the front axle, and your car responds more directly and the unadulterated sportiness cannot be denied. You want to use a strong rebound stage adjustment if you drive with your car through tight mountain roads or long curvy passages.

Remaining comfortable with an extra sportiness

Reduced rebound stage

  • increased ride comfort
  • increased driving comfort

Reduced rebound stage

If you turn the adjustment knob counter-clockwise your ST coilover suspension will dampen and provide more ride comfort than with your standard suspension and traditional lowering springs if you drive on uneven roads most of the time. Therefore, many also refer to rebound as a hardness adjustment instead of rebound adjustment.

Precise handling thanks to adjustable unibal top mounts

unibal top mounts
