ST coilovers ST XA galvanised steel (with hardness adjustment)

ST XA COILOVER KITS

For sporty, ambitious drivers who want to influence more than a continuous lowering, ST Suspensions has developed the ST XA Line in cooperation with KW. The adjustable damper setup allows the driving behaviour to be individually adjusted.

For the sporty, ambitious driver
The adjustable damping characteristics of ST XA coilover kits make it possible to further adjust the damper setup individually. The damping technology used for this comes from KW. It allows the ST XA coilover kits to be adjusted to be firmer or more comfortable, depending on the driver's wishes. The dampers are adjusted at the upper end of the chrome-plated piston rod. If the tensile force is increased, the car drives even more true to track and the body movements are reduced. If a more comfortable damper setup is required, the adjustment is also made via the rebound adjustment. The adjustable dampers also allow for the change to a different rim size. But even in the basic damper setting, a vehicle with an ST XA coilover kit acts significantly more agile and offers sportier handling characteristics than a standard suspension.

Easy variation of the lowering
As with all ST XA coilover kits, the continuous adjustment of the lowering is done via the threaded spring plate. For this, ST Suspensions also uses a polyamide adjustment spring plate, like KW, which allows easy adjustment of the lowering via the trapezoidal thread on the galvanised strut. Changing the lowering is also possible when installed, by simply turning the adjustment spring plate higher or lower. If the car has a non-wheel-guiding double wishbone rear suspension, the lowering is adjusted via the ST Suspensions rear axle height adjustment. For information: the lowering is different for each vehicle due to its design. While older vehicle models such as the Honda Civic (EJ9) can be lowered between 40 - 75 mm with the ST XA coilover kits, a lowering of 10 - 40 mm is still possible with the Audi S3 (8P), which is already very low ex works.

KW Engineering: exclusively for ST suspensions
The high-quality ST XA coilover kits are based on the twin-tube damping principle in low-friction and pressure-resistant damper housings. The dampers are manufactured directly at KW. A monoblock guide and sealing package reduces friction in the damper when the chrome-plated piston rod is retracted and extended. In addition, optimum corrosion protection and multiple sealing of the galvanised strut ensure long driving pleasure with the ST XA coilover kits.
