ST XA Coilover Kit 20-23 BMW M340i

This ST XA Coilover Kit includes everything you need to give your 2020-2023 BMW M340i a significant suspension upgrade. You get the front and rear complete coilover assemblies, featuring galvanized zinc-coated steel struts for corrosion protection and hardened chrome piston rods. The kit also includes composite spring perches with stainless steel inserts, designed to prevent corrosion and ensure long-lasting adjustability. Each damper is tested on a shock dyno before packaging, and the kit comes with a detailed manual for setting the 16 distinct clicks of adjustable rebound damping.

With this kit, you gain precise control over both your vehicle's ride height and its driving dynamics. The adjustable spring perches, made from a durable, friction-optimized polyamide composite with a stainless steel insert, make lowering your car a straightforward process. This composite material prevents oxidation between the strut and perch, ensuring you can adjust the height for years to come, while the stainless steel insert adds strength. The adjustable rebound damping allows you to fine-tune the feel of your ride, whether you prefer a sportier, more responsive setup or a more comfortable cruising experience. ST Suspensions, built by experts at KW in Germany, tests each damper to ensure it meets proper force specifications before it's boxed.

The system also incorporates an elastomer bump stop with an integrated dust protection system. This helps prevent dirt and water from reaching the piston rod and seals, extending the life of the damper. Inside, a multi-layered sealing package, mono block guide system, and low-friction piston band work within the pressure-resistant housing for smooth operation. This kit is designed to provide enhanced road control without sacrificing comfort, putting the finer details of your car's driving dynamics directly in your hands.
