ST LOWERING SPRINGS 30mm/30mm - BMW M135I
Lowering Options: FA/RA: 30/30
Material: High tensile chrome silicon steel
ST suspensions are proud to boast one of the largest applications for sports springs with more than 1000 vehicles now catered for. What’s more, ST sports springs are one of the few lowering springs on the market that (in combination with the standard suspension) will greatly improve the driving behaviors of a vehicle as well as its overall looks!
Performance and style for every car
Made from chrome silicon steel in a cold winding process, ST sports springs are multi-coated with a final expoy coating ensuring an OEM quality and finish. As a result, they withstand a variety of weather conditions all year round. Depending on the vehicle model, ST suspension sports springs will allow a typical lowering of around 20mm on the front axle and 15mm on the rear axle. Some vehicles can achieve a much greater lowering with the VW Golf Mk1 benefiting from 60mm on the front and rear axle! Compared to standard suspension, ST sports springs lower the center of gravity to provide much better driving dynamics and handling. Furthermore, compression and rebound are also reduced which allows the car to drive more agile with reduced body roll.
The ideal spring rate for every car
The spring rates of ST sports springs have been designed to work perfectly with the standard dampers to ensure the driving dynamics are improved and ultimately safe. Vehicle weight, wheel loads and the level of lowering have a huge impact on the rebound and compression of a vehicle so it’s essential this is not compromised. Depending on the level of lowering (for example 20mm, 30mm or 40mm), ST sports springs have different spring rates that harmonize with the standard shock absorbers. Put simply the more lowering, the higher the spring rate.
Great variety
ST sports springs aren’t just available for new vehicles such as the Audi A7 Sportback or Mercedes-Benz E-Class; even classic and rare models such as the BMW M30 and Mk1 Golf will find the perfect sports springs in the ST suspension product range!
