ST threaded springs
For improved appearance and even greater driving dynamics - in original equipment quality
ST coilover spring kits offer an excellent alternative to lowering with conventional suspension springs. Unlike simple lowering springs, they allow you to adjust the ride height without being limited to a fixed setting. Using the ST height adjustment mechanism on which the coilover springs rest, you can set your desired, subtle lowering level even after installation.
The ST coilover spring kit not only gives your vehicle a more dynamic look through lowering, but also improves steering response and the responsiveness of the standard dampers. Thanks to our vehicle-specific spring tuning, all driver assistance systems and even the comfort features of an adaptive factory suspension remain fully functional.
No more 30-30 or 40-40!
While installing conventional lowering springs requires you to commit to a fixed lowering setting from the outset, this is not the case with ST coilover spring kits. Depending on the vehicle-specific application, you can adjust the lowering within the specified range using the polyamide threaded spring collar, even after installation. For example, the ST coilover spring kit for the Audi S5 allows for a lowering adjustment of 5 to 35 millimeters. This eliminates any difficulty in varying the lowering when changing your wheel/tire combination.
Original equipment manufacturer (OEM) quality that convinces
The high-quality chrome-silicon steel springs used by ST in their coilover spring kits are vehicle-specific, with spring rates precisely matched to the respective standard suspension dampers and wheel loads. During the development of each spring kit, we ensure that the spring rates perfectly harmonize with the various damper characteristics of your adaptive standard suspension. Thanks to their high-quality tempering, they, like the ST height adjustment system, offer a long service life.In addition, our scope of delivery for the ST coilover spring sets always includes the vehicle-specific elastomer mounts and a dust protection system to protect your standard suspension from wear caused by splash water and salt.
- Individual height adjustment of the standard suspension
- Adaptive series damper control remains active
- Vehicle-specific spring rates
- Improved steering response
- More attractive appearance
Setup - Application and tuning
ST coilover spring kits are ideal for drivers who want to subtly lower their vehicle while benefiting from a customizable adjustment range. Thanks to these vehicle-specific ST coilover spring kits, the original suspension can still be used and is significantly enhanced.
