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 behaviour 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 Nürburgring 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.
Setup: The individual adjustable rebound- & compression damping of the KW Variant 3 "inox-line"
The KW coilover kit Variant 3 "inox-line" is the perfect accessory for performance-oriented drivers and tuning enthusiasts who put a great demand on their suspension. The separately rebound and compression damping adjustable dampers with their "well-thought-out" click adjustment allow a perfect setup. So it is easy to influence the steering behavior, directional stability, tire grip, and handling characteristics when driving on the limit.
