KW Coilover Kit V1 BMW 4 Series Coupe 228i M440i 4WD XDrive w/electronic dampers

Starting with the INOX-LINE stainless steel construction, these KW V1 coilovers are built to resist corrosion, even when you're adjusting the ride height. This means the dirt-resistant trapezoid threads and composite adjustment collars will keep working smoothly for years, letting you easily dial in your preferred stance. KW engineers have pre-set the damping and spring rates specifically for your BMW 4 Series, balancing sporty handling with everyday comfort.

KW develops each application on the Nürburgring Nordschleife and in their 7-post chassis dynamics test center, ensuring a setup that reduces body roll for more direct handling without sacrificing too much practicality. The kit includes elastomer bump stops with integrated dust protection to keep contaminants away from the piston rod and seals, contributing to long-term durability. You'll also find composite spring perches that prevent oxidation while providing a strong foundation.

This V1 kit is KW's entry into their street performance line, offering a harmonious, pre-configured setup that's ready to go. Each damper is individually tested before leaving their German headquarters, and they come with a limited lifetime warranty for peace of mind.
