You will not only benefit from a lowered center of gravity and more direct handling but also improved steering and more stability during cornering. ST suspensions springs are constructed to OEM quality standards. They are made of high strength chrome silicon steel in a cold winding process then multi-tempered and have a final epoxy coating.

ST Suspensions adjustable lowering springs deliver improved looks and more driving dynamics in OEM quality. The 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. Not only does your vehicle get a more dynamic look, but the steering behavior and response of the standard dampers also becomes more agile. All driver assistance systems and comfort features of an adaptive series suspension remain with these vehicle-specific developed spring setups. Order the springs recommended for your suspension.
• No more 30-30 or 40-40!
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. For example, the ST height-adjustable spring kit for an Audi S5 allows you to lower the car in the range of 5-35mm. You won't have any difficulties adjusting the lowering when changing your wheel/tire combination.
• OEM Quality
High-quality springs made of chrome-silicon steel are at the core of ST coilover spring kits. Their spring rates are adjusted to the respective standard suspension dampers and wheel loads of your vehicle. They 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, the spring kits delivery content always includes the vehicle-specific bump stops with dust protection system to guard your standard suspension.
