Whether you drive a sporty coupe, a daily sedan, or a tuned hatchback, ST coilovers and suspension parts deliver a remarkable transformation, enhancing handling, stability, and overall driving pleasure without compromising everyday comfort.

Overview of ST Suspensions

ST Suspensions, a brand under the KW Automotive Group, combines decades of racing heritage with street-ready engineering. The same innovation found in KW’s motorsport systems is refined and adapted into ST’s accessible performance line. This ensures that drivers experience exceptional handling precision, ride height adjustability, and long-lasting durability - at a more affordable price point.

At Tuning4, you’ll find a full range of ST coilovers, anti--roll bars, and lowering springs, all designed for plug-and-play installation across hundreds of vehicle models.

Performance and Ride Quality Testing

To validate ST’s reputation, multiple real-world and track tests were conducted on popular models including the BMW 3 Series (G20), Volkswagen Golf GTI, and Ford Mustang EcoBoost.

These results confirm that ST coilovers and anti-sway bars not only enhance cornering stability but also preserve daily driving comfort, a true dual-purpose solution.
