From now on you can customize your ST suspensions coilover kit and adapt it to your individual needs. For example you can select your favourite spring colour out of many options or add an additional marking on the springs. For an additional individualization of your spring setup ST also offer optional racing spring kits in different spring rates and lengths for their XTA coilover kits.

Lowering has never been so individual!

ST height adjustable springs kits are a great alternative to conventional springs. You don’t have to be satisfied with a fixed lowering as you can adjust the height with the ST height adjuster even after the kit has been installed.

Your vehicle does not only get a more dynamic look with the ST height adjustable spring kit, but also the steering behaviour and response of the standard dampers becomes more agile. All driver assistance systems and comfort features of an adaptive series suspension remain with our vehicle specific developed spring set up.

With conventional lowering springs you have to decide on the lowering from the beginning, but not with the ST height adjustable spring kits. Depending on the vehicle specific application you can change the lowering within the adjustment range with the threaded spring perch when the springs are already installed. You will not have any difficulties to adjust the lowering when changing your wheel/tire combination.

The from ST used high-quality springs made of chrome-silicon steel are at the ST coilover spring kits in their spring rates vehicle specific adjusted to the respective standard suspension dampers and wheel loads. At the development of the respective spring kits we consider that the spring rates will perfectly harmonize with the different damper characteristics of your adaptive series suspension.

With their high quality (surface) finish as well as the ST height adjuster, our ST height adjustable spring kits delivery content always includes the vehicle-specific bump stops with dust protection system to protect your standard suspension against tear & wear caused by spray and salt.

The ST height adjustable spring kits are suitable for drivers who want to lower their car and have the advantage of an individual adjustment range.
