ST XA Coilover Kit 06-13 BMW 3 Series E90/E92 Sedan/Coupe X-Drive AWD

The spring perch on these ST XA coilovers is made from a durable, friction-optimized polyamide composite with a stainless steel insert. This design helps prevent corrosion between the strut and perch, ensuring that you can adjust your ride height for years to come. The stainless steel insert adds strength where it's needed most. These coilovers are built by hand by experts at KW in Germany, and each damper is tested on a shock dyno before it's boxed up, so you know they're set to perform right out of the gate.

With 16 distinct clicks of adjustable rebound damping, you can really dial in the driving dynamics of your vehicle. Whether you're aiming for a more comfortable ride or a sportier feel, the ST XA coilovers put the finer details of your car's handling in your hands. The galvanized zinc-coated steel struts offer solid corrosion protection, and a dust protection system keeps dirt and debris away from the hardened chrome piston rod and valve packs. This kit is designed to fit a range of BMW 3 Series models, including the E90/E92 xDrive AWD variants like the 325xi, 328xi, 330xi, and 335xi from 2006-2013.

You'll also find an elastomer bump stop with an integrated dust protection system, which helps prevent water and dirt from reaching the piston rod and seals. These bump stops also act as dynamic load limiters while helping to maintain ride quality and durability. The kit comes with a detailed damper setup manual, making it easy to reset to the factory-recommended settings whenever you need to.
