Description
The ST X Coilover Kit is engineered for drivers who want improved handling, a sportier stance, and everyday drivability—right from the start. Designed and manufactured in Germany by KW Automotive, ST X coilovers combine proven suspension technology with durable construction to deliver reliable performance in all driving conditions.
Featuring a continuously threaded coilover body, the ST X kit allows precise ride height adjustment, enabling anything from a subtle drop to an aggressive lowered stance. Ride height adjustments are easily made using a durable polyamide adjustment ring on the galvanized strut or via a vehicle-specific adjustment perch, depending on application.
Developed in collaboration with KW Germany, ST X coilovers significantly improve driving dynamics by reducing body roll during compression and enhancing agility during spirited driving. Each damper features a twin-tube design housed in a low-friction, pressure-resistant casing, paired with a chrome-plated piston rod for long-term durability.
A monoblock guide system and ST’s advanced multi-lip sealing package protect the dampers from dirt, moisture, and road debris, ensuring consistent performance in all weather conditions. The kit includes multi-coated springs, adjustable spring perches, and dynamic elastomer bump stops with integrated dust protection, providing a complete suspension solution straight out of the box.
Backed by ST Suspension’s 5-Year Unlimited Mileage Warranty, the ST X Coilover Kit delivers confidence, control, and unmistakable style for performance-focused enthusiasts.
