Product Description
Ready to ditch the wheel gap? ST coilovers feature a continuously threaded construction for height adjustment from moderate to maximum! Each coilover is manufactured in Germany by KW Automotive. Their expertise and know how ensures maximum quality and fantastic driving dynamics.
Once installed, the ST X coilover can be easily adjusted using a polyamide ring on the galvanized strut or with the vehicle specific height adjustment perch.
Designed in conjunction with KW Germany, ST X coilovers deliver a sporty handling by reducing the car's bodyroll during compression as well as improving agility during spirited driving. The high-quality production of each ST X coilover includes a low-friction and pressure resistant housing alongside a chrome-plated piston rod for maximum longevity. A monoblock guide and ST multi-lip sealing package ensures the twin-tube dampers remain free of dirt particles in all weather conditions.
