For years, the KW Variant 3 'Inox-Line' Coilover Kit has been one of the top aftermarket products and a benchmark for coilovers. It has convinced sports car drivers, tuners, large-and small series manufacturers such as Alpina, MTM, Manthey, Oettinger and many more industry leading companies in the international automotive industry with its damping characteristics, quality finish and durability.

Advanced Technology bred on the racetrack, built for the road.

With the KW Variant 3 'inox-line' coilovers you will get much more than just sporty lowering and excellent driving behavior on all roads. It is based on our long experience as a suspension manufacturer and supplier for international motorsports, such as the ADAC GT Masters touring car series, FIA GT1, FIA GT3, International GT Open, WTCC, VLN, the legendary ADAC Zurich 24h Nurburgring race, as well as IMSA American LeMans Series, now United Sports Car Championship, SCCA Pro Racing and Pirelli World Challenge in North America.

KW Variant 3 'inox-line' coilovers share technology with our race coilovers developed in our KW Competition program, they can be adjusted independently in compression and rebound damping. That possibility of individual adjustment is what has made KW Variant 3 'inox-line' coilover the preferred choice by sports car manufacturers, tuners and drivers worldwide.

The perfect suspension setup for maximum driving pleasure

If you have already made your first performance modifications to your vehicle our KW Variant 3 'inox-line' coilovers will compliment your upgrades. The patented KW-valve technology for separate adjustment of rebound and compression damping allows you to individually setup your suspension. The adjustable KW bottom valve adjusts the low-speed range of the compression level in twelve clicks.

You don't need any adjusting tools because of the patented compression adjuster at the lower end of the stainless steel housing. The adjustable compression damping with its twelve exact clicks allows you to manually influence body roll, without having to change the spring rate which optimally matches the rebound.

With the individually adjustable rebound setup of the KW Variant 3 'inox-line' coilovers, you can directly influence the handling and comfort with its precise click adjustment. The rebound valves of the KW twin-tube dampers on the upper end of the piston rod will be adjusted via an integrated adjustment wheel or a twist-adjustment wheel which is included with the coilover kit.

By increasing the rebound force via the adjustment wheel, the body movements are reduced and adjusts the pitch and roll behavior of the vehicle giving you more stability at increased corner speed. If you change for example the wheel / tire combination (approved by the car manufacturer) to larger wheels, then with a KW Variant 3 'inox-line' coilovers you will be able to adjust the car's handling perfectly.

High quality, individual and durable

The KW Variant 3 'Inox-Line' Coilover Kit and every single damper are subjected to extensive quality tests during production in order to meet the high standards of our KW quality management. This extensive testing is what enables us to give up to five years warranty on our KW Variant 3 'inox-line' coilover when installed at one of our KW specialist dealers. KW coilover struts are made of stainless steel and 100% rust-free with an unlimited life time. Therefore the operation of the continuous lowering via the dirt-resistant KW trapezoid thread and the KW composite collar is also not affected after years. By the individual lowering with its continuous adjustment range, you can emphasize the sportiness of your vehicle visually. A feature that is very popular in the performance-oriented tuning scene.

Structure and function of a KW coilover kit

A KW coilover with its 100 percent corrosion resistant stainless steel strut housings can be height adjusted at all times. With our dirt resistant trapezoid thread and durable composite height adjuster collar adjustment is possible after many years of driving pleasure.

The polyamid composite collar:

In contrast to anodized adjustable spring seats made of aluminum, at KW we use a durable polyamid composite collar with a stainless steel insert. So even with the influence from dirt particles, such as brake dust or sand grains, the polyamide composite collar will not be damaged.
