KW Coilover Kit V2 BMW 4 Series Coupe / M440i 4WD xDrive w/Electronic Dampers

When you're looking to dial in the suspension on your 2021-2025 BMW 430i xDrive or M440i xDrive, the KW V2 "INOX-LINE" coilover kit is a solid choice. This kit includes the front and rear coilover struts, composite spring perches, and elastomer bump stops with integrated dust protection. It's designed to give you more than just a lower stance; it offers a way to fine-tune your car's handling and ride comfort.

What sets the V2 apart is its adjustable rebound damping. Using KW's TVR-A (Twin Valve Rebound - Adjustable) technology, you get 16 precise clicks to adjust how the suspension reacts. This means you can choose between a firmer, more performance-oriented feel for spirited driving or a more comfortable setting for daily cruising, all without affecting the compression damping, which is expertly tuned by KW's engineers for your specific BMW model. The struts themselves are built from Inox-line stainless steel, offering excellent corrosion resistance for long-term durability, and the spring perches are made from a wear-resistant polyamide composite to prevent oxidation and ensure easy height adjustments even after years of use. KW develops these kits with extensive testing, including time on the Nurburgring, to ensure they perform well on your vehicle.

This kit allows for a maximum lowering within an approved range, ensuring your suspension functions correctly and maintains adequate travel. The composite spring perches and stainless steel construction make ride height adjustments straightforward, helping you achieve your desired look and stance. Each kit is hand-built in Germany and comes with a unique serial number, reflecting KW's commitment to quality.
