KW Coilover Kit V2 for BMW X3 F25

Starting with the Inox-Line Stainless Steel construction, these KW V2 coilovers are built for serious corrosion resistance, meaning the adjustment threads won't seize up over time. This is crucial because the V2 system lets you fine-tune your ride with 16 distinct clicks of rebound damping adjustment. You can dial in a firmer, more performance-oriented feel for spirited driving, or soften it up for improved comfort on longer trips, all without affecting the compression damping that our engineers have precisely tuned for your BMW X3 F25.

The TVR-A (Twin Valve Rebound - Adjustable) technology is the heart of this adjustability. It works by controlling oil flow through a conical, low-speed bypass. At low speeds, the oil flows through this adjustable bypass, allowing for fine-tuning of comfort. But when the damper moves faster, a main rebound valve opens up, allowing for maximum fluid displacement. This design gives you a noticeable improvement in ride quality without compromising the high-speed damping that controls body roll during aggressive maneuvers. The kit also includes elastomer bump stops with integrated dust protection, keeping dirt and water away from the piston rod and seals, which further contributes to the long-term durability and performance of the suspension.

KW develops these kits with vehicle-specific spring rates and damper settings, rigorously tested on the Nurburgring and in their 7-post driving dynamics test center. This ensures that even with the adjustability, the foundation of the suspension is solid and performance-focused. The composite spring perches, made from a wear-resistant polyamide with a stainless-steel insert, prevent oxidation and ensure strength, making height adjustments easy and reliable for years to come. This kit allows for maximum lowering within an approved range, ensuring proper suspension function and adequate travel after installation.
