The XTA Plus 3 Coilover Kit for the 2017-2020 BMW 440i Coupe gives your car maximum performance for the road and the tools you need for any challenge. From the factory, the XTA Plus 3 Coilover Kit is equipped with KW dampers that are adjustable in high-speed and low- speed compression as well as adjustable rebound damping. With 24 clicks of adjustment for each, high-speed and low-speed compression damping and 18 clicks of rebound adjustment, your suspension knows no limits. It doesn't matter if you bolt in an aftermarket roll cage, weld in a cage, upgrade to spherical bushing or changed wheel loads - the XTA plus 3 coilover has what it takes to keep your car dialed! Of course, the XTA plus 3 also includes a parts approval certificate, race springs and aluminum uniball 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 adjusting 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.
Standard Features

- Linear race spring system provides a consistent response while driving and makes it easy to swap rates to further personalize your setup.
- From the factory, the XTA Plus 3 Coilover Kit is equipped with KW dampers that are adjustable in high- and low speed compression as well as adjustable rebound damping.
