Of course, the XTA plus 3 also includes a parts approval certificate, race springs and aluminium unibal top mounts. Easy lowering adjustment: Like all ST coilovers the ride height adjustment is made via seamless thread on the galvanized strut housing. This even allows the ride height to be adjusted even when the kit is installed by adjustubg the spring perch higher or lower! NOTE: The lowering of each vehicle differs greatly with ST XTA plus 3 coilovers due to the type of construction. KW Engineering: Exclusive for ST suspension. The high-quality ST XTA plus 3 coilover is based on the twin-tube damping principle of low friction combined with pressure-resistant damper housings. Manufactured directly at KW, a mono block guide and seal package reduces the friction of the damper as well as protecting it against corrosion and dirt. Each galvanized strut is sealed multiple times to ensure maximum longevity in ALL weather conditions.
