ST height-adjustable spring set (coil springs) for BMW X5 (F15, F85) M7X, X-N1, X5 08/2013-07/2018

ST coilover springs

For a better look and even more driving dynamics - in original equipment quality
The ST threaded spring sets offer an excellent alternative to lowering with conventional suspension springs. In comparison to pure lowering springs, they mean that you do not have to be satisfied with a given lowering, but can vary the level of lowering. Using the ST height adjustment, on which the suspension springs rest, you can set your desired discreet lowering when installed.

The ST threaded spring set not only gives your vehicle a more dynamic look thanks to the lowering, but the steering behavior and response of the standard dampers also become more agile thanks to the springs used. Thanks to our spring tuning developed for the respective vehicle, the entire driver assistance systems and even the comfort functions of an adaptive standard suspension are retained.

No more 30-30 or 40-40!
While when installing conventional lowering springs you have to decide from the start on a lowering that cannot be changed later, this is not the case with the ST threaded spring sets. Depending on the vehicle-specific application, you can also change the lowering in the respective adjustment range when installed using the polyamide threaded spring ring. For example, the ST threaded spring set for the Audi S5 allows the lowering to be adjusted in the range of 5 - 35 millimeters. This means you won't have any difficulty varying the lowering when changing your wheel/tire combination.

Original equipment quality that impresses
The spring rate of the high-quality chrome-silicon steel springs used by ST in the ST threaded spring sets is vehicle-specific and tailored to the respective series chassis dampers and wheel loads. When developing the respective spring sets, we take into account that the spring rates also harmonize perfectly with the various damper characteristics of your adaptive series chassis. Thanks to their high-quality coating, they impress with a long service life, just like the ST height adjustment. In addition, our scope of delivery for the ST threaded spring sets always includes the vehicle-specific elastomer mounts and a dust protection system to protect your standard chassis from wear and tear caused by splash water and salt.

• Individual height adjustment of the standard chassis
• Adaptive series damper control remains active
• Vehicle-specific spring rates

Setup - area of ​​application and coordination
The ST thread spring sets are suitable for drivers who want to lower their vehicle subtly and take advantage of an individual adjustment range. Thanks to the vehicle-specific ST thread spring sets, the standard chassis can continue to be used and is significantly upgraded.
