ST XA Height & Rebound Adjustable Coilovers for Select BMW 2012-2021 (F22/F30/F32) w/ EDC - 1822000G

Fits select 2012-2021 BMW 2 Series, 3 Series, and 4 Series models including 228i, 230i, 335i, 340i, 435i, 440i, M235i, and M240i with EDC (Electronic Damper Control).

The ST XA series is engineered for drivers who demand influence over both ride height and damping behavior. Built by hand by the experts at KW in Germany, these coilovers feature an extensively adjustable damper setup that allows you to precisely dial in driving dynamics without compromising street comfort. With 16 distinct clicks of rebound adjustment, you can toggle between a firm, sporty response and a smoother ride with a simple turn of the adjustment knob.

Constructed for longevity, the kit features galvanized zinc-coated steel struts for maximum corrosion protection. The height adjustment is managed via a friction-optimized polyamide composite spring perch with a stainless steel insert. Unlike traditional metal perches, this composite material prevents oxidation and seizing between the strut and the perch, ensuring the threads remain adjustable through years of use.
