The ST suspensions sport springs, made of chrome-silicon steel in a cold-winding process in original equipment manufacturer quality, are multi-tempered and have a final epoxy coating. This means they can withstand a wide variety of weather conditions. Depending on the vehicle model, the ST suspensions sport springs can be used to achieve subtle lowering of, for example, 20 mm at the front and 15 mm on the drive axle on the current BMW M3 (E9x series), an attractive 30 mm on both axles on the Audi A1 or up to 60 mm on the VW Golf I will. When installing ST suspensions sport springs, not only does the body's center of gravity lower compared to the standard suspension, but driving dynamics also benefit from it. In the case of strong steering movements, such as evasive maneuvers and fast cornering, the body structure movements are reduced due to the lower roll tendency. In addition, the compression and rebound is reduced, making the handling more agile.
