Description

Cutting-edge motorsports technology for more performance on the road. With independently adjustable compression and rebound damping the Variant 3 damper setup can be tuned to your own driving preferences or vehicle modifications such as weight, tire characteristics or additional chassis bracing. True performance optimization is only possible with this unique, patented system. For example, the compression damping force can be increased to optimize grip from the tires, or improve cornering behavior and reduce squat without influencing the rebound damping characteristics that are optimally tuned to the spring rate.

The KW Variant 3 "inox-line" coilover kit is the ideal tool for performance-oriented drivers and experienced tuning enthusiasts who place a strong emphasis on the overall performance of their suspension. The Variant 3 features patented TVR-A and TVC-A technology that provides separately adjustable rebound and compression damping. The extensive adjustment range of the independently configurable rebound and compression make it easy to directly influence the steering behavior, directional stability, grip and handling characteristics for confident and repeatable results at the limit of driving dynamics.

With KW Variant 3 coilovers you can achieve maximum lowering within an approved lowering range that ensures a proper functioning suspension with adequate travel after your car is lowered. Even after years of use you can easily adjust the ride height thanks to the dirt resistant trapezoid thread and composite adjustment collar.

KW Variant 3 Coilovers Feature:

  • Customized Suspension Lowering. KW coilover suspensions, KW height adjustable springs, and KW DLC Air Suspensions allow the suspension to be lowered within the vehicle's technical limitations. For example, our Street Comfort products allow for a customized ride height setting with mild suspension lowering from 10 - 50 mm, while the Street Performance products allow the maximum technically possible suspension lowering range from 45 - 85 mm, depending on the vehicle. This means that the suspension can be lowered to suit the personal needs of the user and, depending on the product category, a setting ranging from Comfort to Performance can be chosen.
  • Composite Spring Seat. The KW coilover spring seat, also known as a spring perch, is constructed with a wear-resistant, friction-optimized polyamide composite material encompassing a stainless steel insert. In contrast to the anodized aluminum adjustable spring seats, the polyamide composite material prevents any possible oxidation while the stainless steel insert maximizes strength.
  • Trapezoidal Threads. In combination with the Inox-Line stainless steel coilover struts, this guarantees the long-term functionality of ride height adjustability. In comparison to common coilovers, KW uses a friction-optimized trapezoidal thread which is less sensitive to dirt and requires less force to adjust. Its large cross-section also provides a higher load-bearing capacity.
  • INOX-Line. KW's coilover suspension struts are manufactured from high-quality stainless steel that is rust-proof. In contrast to other solutions, Inox-Line coatings will not wear off while adjusting the suspension making KW coilover struts 100 percent corrosion resistant with an unlimited lifespan. Lowering the suspension using the trapezoidal thread in combination with the polyamide composite spring seat guarantees long term usability. Even after years the ride height adjustability is not affected.
  • Rebound Adjustment. The rebound stage damping is precisely tuned to the respective vehicle at our in-house drive dynamics test facility, delivered in the middle of the range out of the box. Individual customization can be achieved in 16 precise clicks, allowing you to choose between more comfort or more body control. The two-stage patented TVR-A technology allows the oil to flow through an adjustable, conical low-speed valve during slow piston speeds, while during higher piston speeds the main rebound stage valve opens to handle the flow of large volumes of oil. This provides major improvements in ride comfort without influencing the high-speed.
  • External Reservoir. KW Twin-Tube Technology Knows No Limits. The KW reservoirs provide additional oil and cooling capacity for particularly high force systems. The reservoir, which is filled with low gas pressure, can be fitted anywhere and accommodate the adjustable compression valve to provide more working space inside the damper.
  • TVR-A Technology. The two-stage, patented TVR-A (Twin Valve Rebound - Adjustable) technology enables a small volume of oil to flow through an adjustable, conically shaped, low-speed bypass during low damper speeds, while in the case of higher damper speeds, the main rebound stage valve opens allowing a larger volumn of oil to flow. This provides a big improvement in terms of ride comfort without influencing the safety-relevant high-speed range.
  • TCV-A Technology. The patented compression stage valve with TVC-A technology features two separate spring pre-tensioned valves for low and high volume flows. The compression stage which is tuned to the particular vehicle type on our 7-post rig is supplied with a mid-range factory setting. With 12 precise clicks the adjustable compression stage valve can increase or decrease the cross section in the low-speed valve to achieve more or less compression stage damping. At the same time, in the case of sud-den high piston speeds, the spring pre-tensioned needle valve and the spring pre-tensioned main valve open to their maximum cross section, utilizing the blow-off feature to prevent undesired progressive power surges in the high-speed range. This allows for improved bracing of the vehicle body while simultaneously offering more comfort than with con-ventional valve technology in the case of high wheel acccelleration. The compression stage damper setting is always supplied in combination with a separate rebound stage setting, as only one independent 2-way damper setting allows for true performance optimization.
  • KW 7-Post Driving Dynamic Test. Used regularly by automobile manufacturers and international race teams, KW's in-house 7-post drive dynamics test facility is utilized to optimally tune KW coilover suspensions according to the design and target group. The 7-post drive dynamics test facility is essential for fine tuning along with actual on-road evaluation on public roads and race tracks. In objective laboratory conditions, which can be reproduced at any time, we work everyday to give our customers the internationally-esteemed KW driving experience.
  • Technical Component Report. The technical component report is always included in the package and outlines the guidelines for lowering the suspension of the respective vehicle. The technical component report ensures the vehicle remains usable when set within the guidelines provided in the installation instructions, allowing for an inspection and subsequent entry into the vehicle documents to be carried out without any problems. The technical component report also includes precise vehicle classification, requirements, and tips for safe fitting.These reports are required for road legal approval in many countries, check local laws.

KW is the Benchmark for coilovers. KW Variant 3 "inox-line" coilover rewards the sporty driver with its harmonious pre-configured setup. For each vehicle our engineers develop a specific damper setup and spring rate to increase the driving pleasure with an optimal balance of sportiness and practicality. As with all KW coilovers, the engineers at KW develop the vehicle-specific KW damper tuning and spring rates with comprehensive testing on the Nurburgring Nordschleife and in the KW 7-post chassis dynamics test center. You are not buying a mass produced, generic coilover kit, a KW coilover has been developed specifically for your particular vehicle. As a manufacturer, KW uses only its own resources, high quality components and the damper technology that has all developed in-house. With the KW Variant 3 "inox-line" coilovers, body roll will be reduced during compression giving you the benefit of a more genuine and direct sporty handling while driving.
