With the ST X coilover kit you can perfectly adjust the look of your vehicle due to the stepless lowering. We manufacture the adjustable spring perch from a resistant and friction-optimized polyamide composite material with stainless steel insert. Thanks to the composite material, a possible oxidation is prevented, in contrast to anodized aluminium spring perches. This way you can permanently use the height adjustment of your ST X coilover kits.

Simply more driving dynamics due to adjustable rebound damping 

With our in 16 clicks adjustable rebound damping, it is possible to fine-tune the damper setup of your ST coilover suspension in a few manual steps and to adapt it to your requirements. The adjustable rebound damping allows you to individually adjust the recommended setup for your vehicle either tighter or more comfortable, to take influence on the suspension setup yourself. So you completely decide whether the driving behavior of your car shall be tuned even sportier, or rather comfortable. The rebound stage has the purpose to control the relaxation process of the suspension spring and to dampen its vibration.

Adjustable dampers only available at:

Closed rebound stage

Sporty tight and maximum performance

If you turn the adjusting dial into the right direction, you increase the rebound stage and you will get a tighter handling. High rebound forces (closed rebound) improve the handling again, especially on the front axle, and your car drives even more direct and unadulterated sporty. You want to use the closed rebound stage, if you drive with your car over serpentines or long curve passages.

Characteristics at a closed rebound stage

  • More direct steering
  • Improved handling
  • Pitching and rolling movements of the
    body are reduced

Opened rebound stage

Remaining comfort with an extra sportiness

If you turn the adjusting dial into the left direction and when you drive on uneven roads most of the time, your ST coilover suspension will dampen better and you have more ride comfort than for example with a standard suspension and lowering springs. Therefore many also speak of a hardness adjustment instead of rebound adjustment.

Characteristics at opened rebound stage:

  • Increased rolling comfort
  • More driving comfort
