KW Coilover Kit V1 Audi A4 S4 (8K/B8) w/ electronic dampening control Sedan FWD + Quattro

This KW V1 INOX-LINE coilover kit bundles the front and rear struts, along with bump stops and composite spring perches, giving you everything needed to lower and improve the handling of your Audi A4, S4, A5, or S5. It's designed for vehicles with electronic dampening control, and includes a unit to cancel out that factory electronic signal so the new dampers can work properly. This kit is a great starting point for those who want to lower their car and achieve a sportier feel, while still relying on KW's expertise for a balanced setup.

KW builds these V1 coilovers with their INOX-LINE stainless steel struts, which means they're truly resistant to corrosion and will make adjusting your ride height easy, even after years of use. The springs are also corrosion-resistant, and the bump stops have an integrated dust protection system to keep dirt and water away from the piston rod and seals, helping to maintain ride quality and durability. KW engineers develop a specific damper setup and spring rate for each vehicle application, drawing on extensive testing at places like the Nürburgring Nordschleife and their own 7-post chassis dynamics test center. This means you get a harmonious, pre-configured setup that offers an optimal balance of sportiness and practicality, reducing body roll for more direct handling without sacrificing too much comfort.

With the V1 kit, you can achieve a maximum lowering within an approved range, ensuring your suspension still functions correctly and has adequate travel. The composite spring perches are made from a wear-resistant, friction-optimized polyamide with a stainless-steel insert, preventing oxidation and maximizing strength. Each coilover is hand-built in Germany and individually serial numbered, with every damper dyno-tested before it leaves the factory to ensure accuracy and functionality. This kit comes with a limited lifetime warranty for unlimited mileage.
