ST suspensions is proud to boast one of the largest applications for sport springs. Once more, ST sport springs are one of the few lowering springs on the market that (in combination with the standard suspension) will greatly improve the driving behavior 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 sport springs are multi-coated with a final epoxy 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 sport springs will allow a typical lowering of 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 sport springs lower the center of gravity to provide increased driving dynamics and handling. Furthermore, compression and rebound is 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 sport 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 sport 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 sport springs aren’t just available for new vehicles; even classic and rare models such as the BMW M30 and Mk1 Golf will find the perfect sport springs in the ST suspension product range!
