ST 2014+ Coupe 228i/230i (F22/F23) 2WD (w/ Electronic Dampers) XTA Plus 3 Adjustable Coilover Kit

ST Suspensions is known for providing high-performance suspension components that are built with German engineering. This XTA Plus 3 coilover kit is a prime example, offering extensive adjustability for a wide range of BMW 2 Series, 3 Series, and 4 Series models, including popular examples like the BMW 228i, 330i, and 430i. If you're looking to fine-tune your car's handling for both street driving and track challenges, this kit gives you the tools to do it.

What sets this kit apart is the advanced damping control, developed in partnership with KW Suspensions. You get 24 distinct clicks for both high-speed and low-speed compression adjustments, plus 18 clicks for rebound. This level of control allows you to precisely dial in your suspension's response to different road conditions, driving styles, or even modifications like a roll cage or upgraded bushings. The ride height is easily adjusted using a seamless thread on the galvanized strut housing, and the composite spring perches are designed to prevent oxidation and reduce friction. Each strut is galvanized and sealed multiple times for durability in all weather conditions, and the elastomer bump stops include an integrated dust protection system.

This kit also includes linear race springs for consistent response and aluminum unibal top mounts that improve steering feel and allow for camber adjustments where applicable. Everything is built by hand at KW's facility in Germany, with each damper tested on a shock dyno before being boxed. You also get a parts approval certificate for peace of mind. While the lowering amount can vary by vehicle, this kit is designed to give you significant control over your car's stance and performance.
